Of course, all aquariums are different. There are many differences, but the most important is their volume. The remaining differences are associated with the presence of plants in the aquarium or their absence, the presence of certain species of fish and their number. There are a lot of combinations and variations. There are large aquariums with a small number of fish and plants and small aquariums with a large number of those and others. Therefore, for maximum effect water filtration and ensure cleanliness Fish Tank Filter It is desirable to choose strictly individually. However, when choosing a filter, you also need to take into account the material side of the issue. Sometimes it makes no sense to buy a very powerful and expensive device, but you can simply do with a filter of average characteristics and, thus, save a decent amount of money.
Types of aquarium water filtration
Fish Tank Filters in our time it is produced in very large quantities. To understand this volume of production is not all under force. The first and most important thing that is necessary to clarify for an inexperienced aquarist is that there are four basic types water filtration in aquarium. Based on these principles, the filter action mechanism is built, which distinguishes them from each other:
- Mechanical filtration of water.
- Chemical filtration.
The principles of operation of filters with a specific type of filtering should be considered in more detail.
Mechanical water filtration
Mechanical filters for aquarium can be described as the most simple and at the same time the most effective. They are often called "glasses" and this name is explained by the structure of the filters and the principle of their work. The stakan type filter is equipped with a pump (motor) and a sponge that absorbs sewage. The pump pumps the water in the tank and forces it to pass through the sponge, thereby cleaning it. Such simple filtering successfully copes with the removal of large impurities: food residues, fish impurities, dead plants, excess fertilizer for the aquarium, etc. Mechanical water filtration in the aquarium, as a one-component filtering option, suitable for a small aquarium with a small number of non-large fish. That will be quite enough.
Chemical Aquarium Filtration
Chemical aquarium water filtration It involves passing through various absorbent substances. The simplest and most common absorbent is aquarium coal. Other sorbents are applicable, but less common in aquaristics: ion exchange resins and zeolite. Filters containing sorbents are more practical to use and provide better water filtration than simple mechanical filters. The sorbing effect of coal is explained by the structure of its structure. Small pores retain smaller particles, and ion-exchange resins, in addition to sorbing particles, are capable of absorbing dangerous and harmful poisons: ammonia, nitrites, nitrates, and heavy metals.
Since the main cleanliness in the aquarium is maintained by beneficial bacteria, processing all waste and impurities, biological filtration can be considered the most valuable, important and natural. However, bacterial colonies must develop on a specific substrate that is convenient for them. Therefore, in the filter for these purposes, special compartments for ceramics are provided, in which colonies of “beneficial” bacteria multiply. Aquarium aquatic organisms purify water better than any filter elements and chemistry, while making water transparent. Bacteria decompose ammonia, nitrates and nitrites and convert them into gases that are easily removed from the aquarium, thereby reducing the likelihood of fish intoxication and reducing the risk of disease.
Combined Aquarium Filtration
Combined filtration in the aquarium allows you to combine the advantages of all the above methods of filtering aquarium water and, thereby, achieve greater success in its purification. Fish Tank Filters adapted for combined filtration have several compartments. One under the sponge, the second under the ceramic, the third under the sorbing filler. It is even possible to have a special compartment for installing a bactericidal lamp for an aquarium that disinfects water. One way or another, but even a filter with two cleaning functions already has the right to be called a combined one.
Summarizing the above, we can say that if the aquarium is small and the fish do not differ in large size, then it is logical not to go into additional difficulties and opt for the usual mechanical filter for aquarium. And the first advantage of this choice is its relative cheapness and ease of operation. However, if the aquarium is large in volume and large numbers of fish or just large fish live in it, then a combined filter with a biofiltration element is simply necessary. The relative high cost and complexity of the operation of this filtration system pays off its reliability and durability. When choosing Fish Tank Filter Be sure to study its specifications. And the most important of the characteristics of this kind is the power of the Fish Tank Filter. Power filter for aquarium – this is, in fact, its capacity for a certain period of time. The more the filter passes water through itself in an hour, the more powerful it is. All information about the filter power is always indicated on the package.
In the instructions to Fish Tank Filter the manufacturer, as a rule, indicates optimally for what volume aquariums. However, it is better and more practical to always acquire a filter an order of magnitude more powerful than recommended in the instructions. With such an approach, the lifespan of the device will be the most optimal, its service life is long, and aquarium filtration better quality.
The noise level from the Fish Tank Filter
The next important technical feature filter for aquarium, which we should not forget, is its “noise”. High-quality filters, of course, produce some noise, but fairly small. It is difficult to recommend a particular brand in this situation, since the filters of one company, but of different power, are not identical in their noise characteristics. Definitely one can only say that cheap devices should be avoided. Proven trademarks, however, try to adhere to quality and make decent, silent models.
The last aspect of choosing the best filter for aquarium lies in the simplicity of its assembly / disassembly. Many filters are equipped with multiple containers and various nozzles. Often, some of the additional components are inconvenient to clean or simply not useful, so when buying a filter, it is desirable to take into account the simplicity of its further operation. It is advisable to carefully inspect the future filter before final selection.
The location of the filter in the aquarium
The most important difference between Fish Tank Filters and the most important division can be made according to their location. Fish Tank Filters are divided into:
- internal filters;
- external filters;
- mounted filters;
- bottom filters;
- aeration filters.
Internal Fish Tank Filters
Apparently, the most popular, practical, simple and cheap Fish Tank Filter is the internal filter. Such a filter can provide all basic types. water filtration (mechanical, chemical, biological and combined) and located inside the aquarium. They are very simple in everyday use and cleaning, relatively inexpensive. For medium aquariums, they are best suited. However, their main disadvantage lies precisely in the fact that they are located inside the aquarium. Firstly, regular cleaning of this filter leads to some stress in fish, and secondly, the noise from the motor also has a negative effect on the physiological state of the inhabitants of the aquarium. Interior Fish Tank Filter may interfere with its natural composition and reduce the useful volume. All these points of contention are individual and only the aquarium owner should evaluate them. In fact, the drawbacks of the internal filter are not so great.
External Fish Tank Filters
These filters are already more professional tools. water filtration and, as a rule, are used in large aquariums. They are installed outside the aquarium, and only tubes from an external filter are sucked into the aquarium, sucking and feeding water. External filters save a useful volume of water in the aquarium itself, but take up quite a lot of space outside of it, which can be considered both a strength and a disadvantage. The external filters have a larger volume of filter elements compared to the internal ones and this allows them to purify water more qualitatively. Large size outdoor filter for aquarium also implies varying degrees of purification and combined filtration.
The most significant drawback of the external Fish Tank Filter is the probability of its sudden occurrence and the flood trouble associated with it. However, with timely revision of the device such a danger can be easily avoided. Many buyers can also be repelled by the substantial price of the outdoor filter and the large volume occupied by it. But it should be remembered that good equipment cannot be cheap, and the filter itself may well fit into one of the compartments of the aquarium drawer.
Mounted Fish Tank Filters
Hinged Fish Tank Filters are a compromise version of the outer and inner filters. They are not located inside, but they are not really outside, they save space both in the aquarium itself and beyond. And although the opinion of saving space is controversial, some aquarists use these filters with success. These hybrid filters are designed for aquariums up to 50 liters. They have not received wide popularity, but their compactness and appearance sometimes give an aquarium additional elegance.
Aeration (airlift) Fish Tank Filters
Data filters for aquariums especially popular in Western Europe and the United States and only in recent years more widely used in the CIS countries. They are a hollow tube with a filter element at its end (for example, a conventional sponge) and a sprayer embedded inside the tube itself. In fact, it is a combination of a filter element, a tube and a compressor. When the compressor is working, bubbles of rising air create cravings of water and pump it into the tube through the filter element and then bring it back to the aquarium again, additionally enriching with oxygen. Airlift filter is extremely compact and simple – the only tube in the aquarium does not take up much space. Servicing it also comes down to a simple sponge wash, and the lack of a motor minimizes noise from work. The disadvantage is that it is impossible to use an aeration filter in combined filtration and a small (up to 50 liters) volume of an aquarium that it can maintain.
Bottom Fish Tank Filters
Bottom filters were popular at dawn aquaria and in our time are used less and less. Only professionals sometimes use “false” to filter their aquariums, as these filters, for the most part, do with their own hands. Often this type water filtration used for “shrimp”, where the use of conventional filters can be dangerous for its inhabitants. Bottom filter assumes the presence of space under the ground, which is created by the device of artificial bottom. Bottom Fish Tank Filter can work both for water intake from under the ground (classic bottom filter) and for water supply under the ground (bottom filter of the reverse type). Pumps or aeration filters can be used to supply or withdraw water. The filtering component, in this case, is the bottom itself – the bacteria contained in the soil process products of vital activity and act as a biological filter, and the soil itself regularly driven by the flow of water does not lie. Although this type of filtration, in all likelihood, is the most natural, only an aquarist with experience can realize it.
Which of the above filters is the most optimal? Analysis of the material gives the right to argue that for aquariums up to 200 liters of the most optimal filter is an internal filter. For large and very large aquariums suitable external Fish Tank Filters. Do not forget that this statement is relative and the individual wishes of the owner of the aquarium must always be considered.
It is also always necessary to remember a very simple and most important rule in aquarism – there is no filter that can replace the banal weekly replacement of aquarium water.
