Pros and cons of bottom filters

Experienced and novice aquarists use these cleaning systems to pack a variety of capacities and capacities. Is it really worth choosing such a filtering system?

pros

  • Water is constantly circulating.
  • At the bottom of the aquarium, the liquid never stagnates, as it penetrates through the soil.
  • Contaminated capacity slower. Therefore, the probability of occurrence of harmful microorganisms, infections is reduced.

With the help of a filtering bottom system, the root system and the soil is saturated with oxygen. But periodically it is turned off in order to eliminate the excess. A constantly working filter helps reduce nutrients that are necessary for the development of shady plants and algae. Therefore, to use such a filter for a round aquarium with a huge amount of green is not worth it.

disadvantages

In order to carry out the installation of such a system, decorative elements, snags, substrate, fish are removed from the aquarium. It will take a lot of time.

It is difficult to remove organic residues and dirt particles from the substrate using a bottom filter. After all, large elements are deposited in the tube. Therefore, you need to wash them often enough.

For large aquariums, an additional filter is required through which the entire volume of water will pass. Some aquarists use siphons, which are used to remove large organics from a liquid.

Experts recommend using the siphon once every 7–10 days.

In order to ensure the normal operation of the bottom filter, periodically, tubes are removed from the aquarium. They are cleaned of dirt and small stones.

Because of all the above disadvantages, such cleaning systems are used to complete aquariums, the volume of which reaches 45-50 liters.

Construction features

For the preparation of aquarium bottom filters are used such elements:

  • Water pump.
  • Several tubes.
  • Lattices or plates that include small cells.

At the bottom of the tank place the tube. Plates with holes or lattices are placed on them. For stability, the plates are sprinkled with a selected substrate. Spray the bottom filters with fine soil, fine-grained sand is not worth it. After all, the substrate will penetrate into the holes, fill them. As a result, the filter in the aquarium stops functioning.

To increase the stability of the lattice or plate sprinkled with stones, small pebbles.

How does it work?

The principle of operation of the bottom filter for the aquarium is simple. From under the installed plate, the grates with the help of a pump pump out liquid. After this, the aquarium water is filtered. The liquid is cleared of impurities, harmful substances, returned to the aquarium.

The tubes are equipped with openings that are used to collect liquid from the reservoir. Some tubes are supplemented with aerators, through which water is saturated with oxygen.

Bottom filter do it yourself

In order to make a bottom filter in the aquarium with their own hands, various technologies are used. The easiest way is to use water pipes made of polymers or plastic, which have an appropriate diameter (up to 25-30 cm).

Before determining the total length of the system, carry out appropriate measurements of the tank.

To prepare the cleaning system using certain elements. The list includes:

  1. Pipes – 3 pieces. The length of plastic tubes must match the length of the container.
  2. Corners for subsequent connection – 4 pieces.
  3. Tee – 2 pieces.
  4. Sections of plastic tubes – 4 pieces.
  5. Funnel for installation of the filtering component.
  6. Plastic separator.

To build using a standard scheme. The pump is placed in a pipe in which small holes are prepared. To ensure thrust, the number of holes on the other side increases. After that, the pipes are covered with a plate made of organic glass or plastic.

The designed cleaning system is installed in the tank in 2–4 hours.

What cleaning systems to use?

Some aquarists do not use bottom structures. To remove impurities, they use internal, external devices.

External models are used to complete the containers, as large-sized, small containers. They are complemented by compressors, other units. The level of their effectiveness is quite high.

Internal cleaning systems installed in tanks, the volume of which is 70 liters or more. They are completed with various elements, accessories. Such a device works around the clock.

Bottom constructions are beneficial for use because the cleaning fluid is carried out naturally. Some aquarists do not use such products, as they have certain disadvantages. Evaluate their effectiveness will be those people who have small tanks with low walls.

What is a bottom filter for an aquarium, how it works

Bottom filter is a device for water purification, which is used in aquariums of different sizes. In another way it is called "false." Water is purified in a natural way, that is, through the soil. With this method, all the garbage remains on the surface of the soil, which is regularly washed.

What is a bottom filter

The design of this filter is quite unusual and consists of the following elements:

  • Thin plate with small holes.
  • Pump for pumping water from under the plate.
  • Tube system

The tubes are placed on the bottom of the aquarium, a plate is placed on top, and then a layer of soil (pebbles or small pebbles).

In no case can not use sand or shallow soil, because they will clog the holes through which the circulation of water flow occurs.

The principle of operation of the bottom filter

False work according to the following principle:

  • By means of a pomp water is pumped out from under the ground.
  • Clean it and then return it back to the aquarium. In this case, the cleaning material are special elements for filtering or directly the ground.
  • After that, the water again begins to seep through the ground and everything starts anew.

Should consider in more detail the principle of its work.

Bottom filter installation

First, the aquarium is drained with fish into a separate container and rinsed with warm water. Also, the soil is washed in warm water to remove residual sludge. A pump is fixed onto the plate with a mechanical cleaning cartridge, and then the filter plate is placed on the bottom of the aquarium. Then make the installation of the grid on the supporting elements and fix the tubes that provide the movement of water through the pump.

If the design provides for a filler, it should be installed. Organic matter that passes through it undergoes mechanical filtration. Large particles of silt fall into it in a very small amount, due to the size of the gaps between the soil. Small organics are well processed by bacteria.

The tube through which the water is discharged is attached to the wall of the aquarium using suction cups or a special attachment. The water flow from the tube should flow out in the form of a fountain, this additionally saturates the water with oxygen.

A pump with a cartridge for mechanical cleaning is masked with a layer of soil. The filter screen is first filled with the largest particles of soil, then with small particles. The net should be pushed to the walls of the aquarium so that the fish that dig the ground do not fall under it.

After this, the aquarium is filled back with pumped water, plants are planted and fish are released.

Bottom filter is mainly used in small aquariums, because in this case its installation does not present great difficulties. Every few months, it is well cleaned and washed.

When installing such a filter, you should take into account the fact that some aquarium plants do not tolerate the constant movement of water at their roots. In addition, the roots of plants regularly receive oxygen, and this in nature does not happen.

In the soil accumulate nutrients that feed the roots of various underwater plants, and the constant filtration can flush them out. Because of this, bottom filters should not be installed in aquariums with rich vegetation.

Types of filtering bottom filter

Standard filter performs mechanical and biological water purification.

Biological filtration is extremely necessary for water purification, because in this case the compounds that are formed during the breakdown of organic matter by bacteria are removed from it. Bottom filter provides a high level of biological water purification. To make it more efficiently cleaned, fillers are used, which increase the area of ​​bacterial colonies.

During mechanical filtration, soil is involved on the surface of which sludge particles are deposited, subsequently penetrating into the cavity below it.

Advantages of bottom filter

This filter has certain advantages:

  • With it, the circulation of water in the aquarium occurs continuously.
  • Passing through the ground, the water does not linger there for a second.
  • Constant water movement does not allow the aquarium to quickly become dirty and does not allow various infections to appear.
  • Such a fake is completely unnoticeable under the plate.
  • For fish creates an optimal microclimate.

Lack of bottom filter

In addition to the advantages, it has false and cons:

  • The surface of the ground still contains dirt and debris of large sizes that can not pass.
  • Garbage very quickly clogs the holes in the tubes. To clean them from the aquarium, pour out all the water and disassemble the structure.
  • It is not recommended to install in aquariums, where many algae grow.

How to use the bottom filter for the aquarium.

Bottom filter (UGF, RUGF) is widely used in fish aquariums. Regarding its use in the aquarium with plants, there are constant, non-ceasing disputes. Some things grow well with the use of a bottom filter, others fail. Of course, in addition to the presence or absence of a bottom filter in an aquarium, there are many other factors that influence plant growth. However, we can say that the use of such a filter has a minus (in addition to the other minuses that any filter has) that nutrients from the soil are washed into the water, where they become food for algae. In a plant aquarium, this is more critical. My practice has shown that the use of a bottom filter will not lead to better or worse growth of plants, while other conditions are fulfilled (light, fertilizer, etc.). It will make the system more unstable, i.e. if you overlooked something, the algae will appear faster than in an aquarium without such a filter. Usually it is necessary to increase the thickness of the soil (bottom layer, when laying the soil in layers). You should also make sure that the gravel does not fall through the filter board, for example, put a grid. Unfortunately. This leads to a decrease in the efficiency of the filter.

How To Make The Most Bottom Filters For Your Aquarium Bottom Filter For An Aquarium

You can refuse to use the bottom filter in its original form and use it in a slightly modified form. Used fee from the bottom of the filter and two tubes. In one, water rises using a pump. The other is open, you only need to put a grid with large holes so that the fish do not swim out. Through this tube, water is sucked under the board. In this scheme, the pumping of water through the ground practically does not occur (in a long aquarium, you can do several intake tubes).

Do not put a sponge or filter on the intake tube, since as water is polluted, the flow of water through these openings will be limited, which will lead to water being pumped through the ground.

This scheme does not have the disadvantages of a bottom filter. True, it does not filter. Its advantages include:

  • The lower layer of water is saturated with oxygen, which reduces the likelihood of the formation of oxygen-free areas in the soil.
  • Down comes warm water from the aquarium. This leads to a more uniform temperature in the ground. Many plants like to keep their feet warm. You can additionally put a weak heating pad (5-10 W) for water heating. A stronger heater would create a backflow of water in the intake tube.
  • CO2 can be introduced into the intake tube if you use it. At the same time, you can see how the bubble tries to rise in a downward flow of water and dissolves rather quickly. True, I later abandoned this method due to the fear of creating water with a low pH under the ground while dissolving CO2.
  • In the initial period, you can close the intake tube and pump water through the ground. This will lead to more rapid decomposition of peat and earth in the initial period of launching the aquarium.

It should be noted that such a system must be cleaned, because after some time it will begin to overgrow with dirt and bacteria under the filter board. This can be done using a brush on a long wire, which is inserted into the intake tube. You can also insert a hose into which to pour water from the tap, and pump water from the second tube out of the aquarium. The hose should be driven under the filter plate to better remove dirt. Therefore, do not put the grid at the bottom of the tubes, which are usually included in the set of such filters – it will interfere with cleaning.

How to make a filter for the aquarium do it yourself

No experienced aquarist will dare to breed fish without the necessary equipment to equip the aquarium. And a special role here is played by the filter, which is used for mechanical and biological cleaning of water, as well as for enriching it with oxygen.

But it is not at all necessary to buy an expensive device, it can be done on its own. The list of necessary details will depend on the type of filter, as well as on the size of the aquarium.

And if you’re wondering how to make a silent filter for the aquarium yourself, this article is for you.

How to make a home external filter for the aquarium

Consider one of the options for making a homemade external filter for the aquarium.

The scheme of construction works as follows:

  • the filter takes a cylindrical shape, the device will be positioned vertically,
  • The electric pump is responsible for the movement of water, which must be installed at the top of the structure,
  • water flows from the bottom of the structure through the fillers, and then goes back to the aquarium,
  • filter materials – various filler options are possible.

For the manufacture of the device will require:

  • two plastic pipes joined together with a rubber cuff inside,
  • two plugs for pipe ends,
  • choke,
  • tap,
  • electric pump,
  • nuts
  • FUM tape,
  • wrenches in the set.

How to make a silent filter for the aquarium

The following materials can play the role of filtering fillers:

Sinteponovye and foam elements: the cheapest and most affordable. They can take any form, and also play the role of a biological and mechanical filter. There is enough space in the pores to settle the bacteria. Periodically, the material should be flushed from clogging mucus.

Also, sludge particles will linger in the pores; in no case should it penetrate into the filter and interfere with its operation.

Filter wool: inexpensive filler that can be used several times, easy to rinse, tightly fills the entire space, eliminates leakage. It is optimum for use as the final stage of mechanical cleaning.

Ceramic tubules: used for colonization of bacteria in small pores.

  • Zeolite: cheap, but very effective sorbent, quickly absorbing ammonium from water. Allows you to quickly get rid of nitrates in the aquarium.
  • Activated carbon: the need to use this filler is still being debated. For use in aquariums, only coal with small granules is suitable, and the number of pores is important, because the absorption efficiency depends on this indicator. Also, the quality of coal can be ascertained by the presence of dust and characteristic luster. Rinse thoroughly before placing material into the filter. It can only be used in a newly launched aquarium.
  • Peat: a natural filtering material donated by nature. It is inexpensive and effectively copes with a number of tasks – reduces the growth of fungi, has a positive effect on the condition of the inhabitants of the aquarium, lowers the pH level.
  • Step 1

    In the lower part of the pipe it is necessary to make a hole for screwing the nozzle. It is necessary to wind its thread in advance with a FUM tape. From the inside you need to twist the nut.

    To ensure that the water inlet opening is always free, it is easy to make a cap with small holes from a plastic bottle, and to attach a grid with holes from a CD over the top.

    Step 2

    On the grid you need to put the fillers in two layers each, alternating with each other.

    To hold the pump fit a piece of hose that attaches it to the water outlet fitting.

    Step 3

    The water intake tube must be fixed with a sucker on the back wall so that one end rests on the bottom. It is enough to hang up the tube for bringing water to the aquarium to the aquarium, slightly lowering it into the water.

    In this model, a homemade filter practically doesn’t catch the eye of the tube, the place in the aquarium remains completely free for its inhabitants.

    This filter with a height of about 40 cm, a pipe diameter of about 10 cm, a volume of about 3 liters passes 5 liters in just one minute, while not creating a strong movement of water flows.

    How to make an internal filter for the aquarium at home

    Internal filters have a simplified structure, so making them with your own hands will not be difficult even for an inexperienced aquarist.

    For the manufacture of the internal filter for the aquarium are required:

    • a plastic bottle, for example, from a soda, with a volume of 0.5 liters,
    • piece of sintepon,
    • plastic tube that matches the diameter of the neck,
    • pebbles for filler,
    • hose and compressor.
    1. The bottle should be divided into two parts, but so that one is smaller than the other. A smaller part should remain with the neck. The bowl must be directed upwards with the neck and with force, so that the construction is dense.
    2. Then along the outer circumference it is necessary to make holes for the entry of water. Their diameter should be about 3-4 mm, it is better to place in two rows of 6 holes in each.
    3. Next, in the neck of the bowl you need to insert a pipe. At the same time between the neck and the pipe can not leave gaps.
    4. The length of the tube should be enough for it to protrude slightly above the surface. But the design itself should not lie at the bottom, so as not to impede the flow of water.
    5. On the bowl on top you need to fill a layer of gravel, and then a layer of synthetic winterizer. Next in the tube you need to install the hose and secure. This design should be placed in the aquarium. After the compressor turns on, the device will work. After some time, live bacteria will appear in the device, which are necessary to dissolve ammonia into nitrates.

    The principle of operation of the filtering device is as follows: it is completely based on airlift. Air bubbles penetrate into the tube, and then move up and sinking water flows.

    Oxygenated water penetrates the upper layers through the gravel, then moves through the holes made downwards and goes down the tube to the aquarium. The task of cleaning is performed by the sintepon, it will help the gravel not to silt.

    Bottom filter for aquarium do it yourself

    Consider several options for bottom filters that are suitable for small aquariums up to hundreds of liters. According to these schemes, you can also make a bottom filter for a round aquarium.

    Bottom filter from plastic box

    The body of the device will be performed by a durable plastic box with a lid that tightly closes the box on top. In this case, it is desirable that either the body itself or the cover is well viewed so that the level of contamination can be monitored.

    A plastic tube should be glued into the cover. On the side wall, you need to make a few holes, but such that through them the small inhabitants of the aquarium are not sucked into the filter.

    Bottom jar filter

    As a body for the future construction, a conventional glass jar with a volume of up to 1 liter will be used. It must be tightly closed with a plastic lid and a hole must be made in it so that the water goes inside and also a hole for the tube.

    From one more cover it is necessary to make a partition and to lay filtering material.

    A ceramic vessel filled with quartz sand and nylon filaments can replace a glass jar.

    Bottom filter for aquarium

    Experienced aquarists know how important a properly selected bottom filter for an aquarium is for normal water treatment. But how to choose a good device for someone who is not a professional? Our review will help our readers understand the variety of filters and select the one and only one you and your fish need.

    Why do you need a filter?

    An aquarium is a complex biological system in which not only fish but also numerous plants and microorganisms live and breed. All of them consume food and take its remains to the outside along with other waste products. In the natural environment, in rivers and lakes, seas and oceans, all this is gradually processed by all participants in the food chain.

    But in the closed space of the aquarium, food debris, waste and other debris accumulate at the bottom. Malicious microorganisms appear in them, which find here an excellent nutrient medium and begin to multiply. As a result, the water becomes cloudy, an unpleasant odor appears in the aquarium, algae start to die, fish get sick and die.

    To prevent this, and need a filter for water purification. Without it, you, our dear readers, will have to constantly change the water and clean the aquarium by hand. And it is rather long and troublesome. Especially if your home water reservoir is rated for 500-700 liters or more.

    And now, having figured out what the filter in the aquarium is for, let’s see what types of water purifiers are used and how they differ from each other.

    Filters are different

    All systems for water purification act on the same principle – the liquid is forcibly pumped out, run through the filtration system and returns back to the aquarium. In some models, water is supplied with air, which saturates it with oxygen.

    To maintain a home water reservoir aquarists use the following types of filters:

    Consider each model separately. The mounted filter is installed in the lid of the aquarium or on top of it. Water is pumped through the pump that is inside. Such models are recommended to be used in tanks with a capacity of no more than 300 liters. The fact is that these filters have low productivity and cannot cope with large volumes. But they are well suited for a small round aquarium.

    External filters are designed for large aquariums. The containers with cleaning elements are hung on the outer wall, and the pump, which pumps water, is located inside. Such systems in addition to mechanical cleaning and perform the function of biological purification. They have another good feature – they are easy to clean and change the filter elements. Therefore, such devices are convenient to use for water purification in a large aquarium (from 1000 liters and more).

    The inner one differs from those described above by the fact that it is inside, in the water. The pump and the cleaning device are located in the same housing. It is very well suited for a small home pond, for example, a classic round aquarium. The disadvantage of such systems is that you need to climb into the water for cleaning. But this is perhaps the only drawback of such purification devices.

    And finally, the fourth type – bottom. It is fundamentally different from the above described principles of location and device. It is made in the form of a plate, in which the cleaning element is located, and holes are made in it for air to escape. On the advantages and disadvantages of such a filter, we will discuss below.

    Pros and cons of the bottom filter

    Why did we select this type of filter? He has an undoubted number of advantages. But first, let’s get acquainted with its shortcomings.

    Perhaps the most serious – difficulty when cleaning. After all, such systems are at the bottom, under a layer of soil, and they are quite difficult to get to clean up the accumulated dirt. Therefore, to clean the bottom filter for the aquarium, you will have to carry out a general cleaning in it.

    But experienced aquarists are not advised to arrange such procedures too often. The fact is that with time in water a peculiar ecological balance is established.

    If the fish do not overfeed, the water will remain clean for a long time. After all, the main cause of pollution of aquariums is not the vital activity of fish and other inhabitants, but the excessive generosity of the owners. Part of the feed that has not been eaten falls to the bottom and slowly begins to decompose.

    It creates an environment for the development of microorganisms, which cause water turbidity, as well as the appearance of an unpleasant odor. This leads to fish diseases and their death.

    Let’s return to our bottom filter. In addition to the difficulties with cleaning, you will also have to tinker with its installation for quite some time. But perhaps this is all the flaws of such systems. But the advantages are much more.

    The first is that such a filter is more efficient than surface ones.

    He not only cleans the water, but also collects from the ground all the remnants of the life of the inhabitants of the aquarium.

    Therefore, the good purity of the artificial reservoir will be maintained longer.

    The second – the filter hidden under a layer of soil is invisible. All his communications are made of transparent plastic, and you can admire the inhabitants of the water world without any interference.

    Third – the bottom cleaner can be installed in any aquarium, including in the round. Other filter systems in this will look somewhat inappropriate, do not you find?

    Secrets of a beautiful aquarium

    And now, after recommending a bottom filter as a system for water purification in a domestic pond, we’ll tell you what it takes to always look great.

    The soil in the aquarium should be medium or large – fine sand will fall into the holes and clog the filter.

    In order to touch the cleaning system as seldom as possible, from time to time you should select a part of the water from the aquarium and replace it with fresh, previously settled.

    Bottom Reverse Filter – Aquashrimps.ru

    I thought for a long time which bottom filter to assemble for a shrimp on a special ground, classic or reverse type.

    • Bottom filter classic – works on water intake from under the ground. It is possible to pump out water both a pomp, and an airlift.
    • Bottom filter of the reverse type – works on the water supply under the ground. For pumping water pump is used.

    The flow of water in both cases does not need a strong one, since the meaning of the bottom filter does not allow stagnant zones to form and improve biofiltration, as well as accelerate the decomposition of organic matter in the soil. I chose the bottom filter of the reverse type, relying on the advantages that I saw in the use of this system. In it, the entire area of ​​the bottom is an active biofilter without stagnant zones (similar to that of the classical system). Throwing water under the ground, we install a prefilter (sponge) on the pump, and in turn it filters out the bulk of suspended matter and other debris, after which mechanically purified water flows under the ground. This process allows the soil to remain clean for a long time.

    Also, weak streams of water do not allow the ground to silt, all the dirt falling on the ground, gradually dissolves and rises from it into the water and is filtered by prefilter.

    In the classical system, the entire soil is both a biological and mechanical filter. Although this system is also not much silted, if the correct population is chosen, which will not be very shit. And then the classic bottom filter will get rid of and the ground will remain fairly clean for a long time. Bottom filter systems also make it possible not to siphon the soil, which is also important for shrimpers. But even if it is strongly impatient, and there will be a lot of dirt on the ground, the reverse system can be easily cleaned by adding the power of the pump and siphoning only the surface of the soil. With the classical system such a move is not possible. This also served as a pretext for the manufacture of a reverse system.

    To make a bottom reverse current filter, for an aquarium, 45x45x45cm, I needed:

    1. Polypropylene pipes 20mm 2.5m
    2. PVC corners for cable channels 20mm 4pcs
    3. PVC tee for cable channels 20mm 1pcs
    4. Plexiglass sheet, perforated with a 5mm drill (the more holes the better)
    5. The grid is mosquito.
    6. Chinese pump at 500l / h with adjustable flow.
    7. Different tubes and a corner to connect the pump with a polypropylene pipe (picked up from the existing junk).

    This is what the bottom filter without a pump looks like in the photo:

    The arrows indicate where the holes were drilled (5mm). The system works purely for the water supply under the ground (the flow is reduced in two), since there is another filter with flute for mixing the water. We have been working for a month and a half, while there were no problems, I like everything, the shrimps also reproduce normally.

    I know similar aquariums with bottom filters of the reverse type, which have been operating for more than a year and have no problems, the ground is clean! Here is an example of a backflow bottom filter with flute added. Where the flute serves to mix the water in the aquarium, without adding an additional filter. And also serves to reduce the flow of water supplied under the ground! Such a system does not require flow adjustment. Also in this system, more suitable pipes were used, namely xpvh 16mm, I unfortunately did not find such, I had to do from 20mm ((

    Which bottom filter for aquarium is better, what is it for?

    Home / Fish / Maintenance and care / How to make the most bottom filters for your aquarium?

    But rarely anyone realizes that behind the cleanliness of the aquarium there is the hard work of complex devices – Fish Tank Filters, which, while in the shade, do the main job of ensuring cleanliness in our aquariums. Let’s see what the aquarium bottom filter is and why it is needed.

    Bottom filter

    What are the classification of filters for use in the home:

    A lot of manufacturers and brands in the market of modern aquarists provide the buyer with a choice of a huge number of types and models of filters, but today our conversation will focus on bottom filters and there are several reasons for that. We will consider the question from the average buyer.

    Unconditionally advantages of the bottom filter are:

    1. Noiselessness
    2. Continuous circulation.
    3. Stealth device.
    4. High level of biological and mechanical cleaning.
    5. Affordable price.
    6. Creating in the aquarium the necessary microclimate.

    These are the main advantages of the bottom filter over competitors, but not the only ones.

    Why do you need a filter

    Soviet-time aquarium enthusiasts remember goldfish aquariums, in which there was nothing but glass and the fish itself. And pets lived, just getting air and food, and lived happily ever after. What has changed since then?

    Where did the need for complex devices come from? The thing is that over time, lovers of colorful waterfowl pets want a variety and the choice of simple guppies or veil tails falls on more exotic fish. And here the future owner is faced with the fact that the content requirements of some species are much higher.

    Fish Tank Filter performs one of the most basic functions in an aquarium – biofiltration. It is inside the device and reigns life at the micro level, which works on the purity of the aquarium.

    Beneficial bacteria that live inside recycle excess feed and fish waste products. By processing this, they eliminate the aquarium from being oversaturated with harmful substances, and enrich them with substances useful for fish.

    Bottom filter device

    How are the bottom filters?

    The most advantageous advantages of such devices is the price and architecture. If, from the price side, it becomes clear that by attaching not very much finance and a little time, you will make a device with your own hands, then the question of architecture is a bit thinner.

    In order to assemble the bottom filter at home you will need:

    1. PVC pipe.
    2. PVC corners.
    3. Pvc tees.
    4. Stainless steel clamps.
    5. Pumps depending on the complexity of the system.
    6. Construction tools (drill, hacksaw, stationery knife).

    And, of course, the drawing and calculations of your future filter element. Plexiglas can be used as a grid, holes in which can be made with a drill. A little better for this task fit soldering iron. When working with a drill there is a chance that the plexiglass may burst.

    The holes in the pipe should be about 1 cm in diameter and often be drilled for better water flow. And it is worth considering that the farther from the pump, the holes should be closer to each other, since the pump will give the main pressure near the direct installation site.

The bottom filter is not always in small aquariums can create an optimal water flow. And vice versa – if the pump is selected too powerful, then the water flow will be too powerful. But the most important negative feature is the need for periodic cleaning.

    If the rest of the listed filters are either quickly dismantled from the aquarium, or do not require intervention in it at all, to remove the bottom filter, it will be necessary to free the aquarium completely from fish, plants, decor, water and soil.

    You can avoid this by remembering one simple rule – you should not overfeed the fish. No matter which device the filter is, not one of them is able to cope with overfeeding without the need for frequent cleaning. Moreover, overfeeding leads to overeating of fish and its possible death.
