Purpose and Description

As is well known to anyone interested in aquariums, the axiom is the need to clean the aquarium water. And if the water in a river or lake is purified in a natural way, this method is not applicable in aquarism. Therefore, the water in the tank should be cleaned artificially. The normal existence of all aquatic inhabitants, be it ornamental fish or plants, mollusks or crustaceans directly depends on the quality and purity of the water in the tank.

By type of filtering

There are biological, chemical and mechanical types of filtration of aquarium water.

This classification separates the filters for the aquarium. There is also a water purifier that uses all three types of cleaning at once. This is an external canister filter. But the need to use all types of cleaning at once is not necessary. For an aquarium it will be enough to filter one type. Let us consider in more detail the types of filtering.

Mechanical filtration purifies water with a filler. Dirty water enters the filter, particles of debris and dirt are deposited in the pores of the filler, and the output is water that is free of debris. Thus, the filler accumulates particles of debris. A sponge or a bundle of tangled fishing line can act as a filler. This type of filtration is suitable for aquariums in which goldfish and cichlids live.

Biological filtration no less important for an aquarium. With its help, the aquarium gets rid of toxic substances, which are formed as a result of the vital activity of fish and plants. This type of filtration allows you to keep an aquarium with healthy fish and vegetation.

Biological filtration is performed by special bacteria that live in the soil. Also, special fillers for water purifiers are used as biological filtration. In such fillers live colonies of bacteria that purify water from toxins.

Chemical filtration allows you to remove waste from the water thanks to activated carbon. Water passes through a carbon filter and absorbs phosphates and other impurities and minerals. With the help of such a filtration ammonia and an unpleasant smell leave the water. This type of cleaning is very effective and helps to obtain a high degree of water purification.

By way of installation

According to the construction format, there are several types of water purifiers:

  • external;
  • internal;
  • canister;
  • bottom.

External filter placed outside the aquarium. Usually it is placed in the nightstand under the aquarium, or it can be attached to the side or back wall. This placement makes it easy to care for and clean. The device is divided into compartments. Such a water purifier can combine all three types of filtration, since it is possible to load different types of filler into different compartments.

Internal filter – This is a small size design with pump and filter media. Foam rubber is most often used as a filler. It is placed inside the aquarium, mounted with special suction cups on any convenient wall. Such equipment uses only mechanical type of filtration and needs frequent maintenance. Very popular with home aquariums.

The most important criterion for choosing a water treatment device for your aquarium is its power and performance, that is, how much liquid the device can pass through itself in 1 hour. On the packaging of the device there is always a label with a capacity value – 300 liters per hour, 1000 liters per hour, etc.

If you are not interested in understanding the calculations of the power of the water purifier for a specific tank – you can see what volumes the manufacturers write on the packaging of the device. However, this value is not always true. Such an estimated power is calculated by the manufacturer under conditions close to ideal, namely in pure water, in which there are no impurities and fillers.

By filter type

The most popular and used in aquariums is the internal filter device. Such water purifiers are very easy to use and inexpensive, but occupy useful space in the tank.

In contrast to the internal water purifier use external. In the tank, only 2 tubes are lowered through which water is purified. The undoubted advantage of such cleaners is their high performance. In addition, they are devoid of the shortcomings of domestic appliances. However, external filters are more expensive and larger in size than internal cleaners.

Compromise between the two previous devices will be mounted cleaner. It is attached to the wall of the aquarium, and the filter device is in the tank. True, these types of filters are not very popular.

It conducts cleaning both through the soil and through the filter element, so the liquid is cleaned twice. However, the bottom cleaner is less productive and more difficult to maintain than other types. For these reasons, they are bought for small aquariums.

By filler material

Sponge is the most popular element for a water purifier. Small-pored and large-pored sponges trap mechanical debris (leftover food, plants, foreign objects) in themselves when the water forcibly passes through them. Such sponges in a week settle down useful bacteria that act as a biological water purifier and purify water from nitrates and methane. The term for cleaning these filtering components is usually indicated on the instructions for the device; on average, the sponge should be cleaned once every 2 weeks.

More qualitatively, than a sponge, water in an aquarium is cleared by absorbent carbon. The truth with this type of water purifiers must be remembered that when activated carbon is over-saturated with harmful substances, it will itself emit them back.

After you properly fix the device – turn it on the network, and the wire should not be stretched, but fall freely. If there is a flow of water – you did everything right. At the outlet of the liquid in the water purifier is a damper, which regulates the power flow and direction of water. If you want to correct it or change the direction of the water, first turn off the device from the outlet. Biological water purifier during installation has certain subtleties. In order for it to settle the necessary bacteria on the sponges or filler device, use a special drug that allows bacteria to develop faster.

Exploitation

All filters require cleaning and maintenance. For normal service of the equipment, it is necessary to clean it regularly. The efficiency of the clogged filter is reduced regardless of its type. In order to determine how often it is necessary to clean a water purifier, you need to remember the following rule: the smaller the water purifier and the greater the load on it, the more often it must be washed.

The exact frequency of cleaning the filtration system is determined according to the parameters of the tank and the type of filter.

Water purifiers with a mechanical type of cleaning often need to wash the filler. Typically, this procedure is done 1 time in 2 weeks. To do this, turn off the filter, remove it from the aquarium, remove the filler and wash it under running water. If the aquarium clogs faster, then cleaning the filter should be done more often. Biological water purifiers are washed much less frequently. They are washed in parts (approximately 1/3) every 3 months. General cleaning is not carried out. In order to preserve the colonies of bacteria, you need to leave a little old substrate.

If a water purifier with chemical cleaning is installed in the aquarium, the coal used over time needs to be replaced. Activated carbon absorbs organic matter well on average from 2 to 4 months. More accurate calculations are hard to make, since the purity of the water in an aquarium depends on many conditions.

According to many experienced aquarists, water treatment is an essential part of aquarism. Therefore, every lover of ornamental fish needs to know how to choose the right water purifier, install a filter in the aquarium and continue to operate it correctly. When choosing Fish Tank Filters, it is necessary to take into account the volume of water, types of fish and plants. Properly selected filter will allow the inhabitants to live in comfortable conditions and facilitate the care of the aquarium.
