All lovers of home aquarium are united by one idea: to create the aquarium, which will be pleasing to the eye with bright, healthy fish, beautiful plants, decoration and harmoniously fit into the room. As a rule you can buy all these things in aquarium shops.
The filter in the aquarium is very important item among all aquarium parts, it performs several functions. The most important of these are: purification of water from dirt particles and pollutants and the creation of flow and oxygenation. The designs of filters are many: simple interior ("glasses"), external (canister), hinged,
Sampo, and so on, but they have one principle of action: pump runs the water through the compartments with the filter materials. You should buy a filter with multiple compartments. At first the water is cleared of turbidity passing through coarse or fine sponge - so committed mechanical water treatment. Then water is sent to the biological treatment compartment.
Over time there formed colonies of nitrifying bacterias, which convert harmful ammonia, a product of fish waste into less toxic substances. This area must be a special filler - for example, zeolite or "biological ball".
If it is more filler, surface area is bigger, more beneficial bacterias will settle there, which has a positive impact on the biofiltration aquarium. The same or the next compartment can be activated carbon and other special remedy of absorbing harmful chemicals from the water. If in the filter are not additional compartments, bacterias will settle on the sponge. For this reason, you should not buy a tiny filter with the minimum volume of the filter material.
Also, the power pump is important. Ideally, it should be pumped 5-10 tank volumes per hour. The manufacturer usually specifies this option on the packaging.
Type of filter depends on the type of aquarium. For mini-aquariums fit small external, mounted filters, internal filters. Some manufacturers insert in filters of different designs on the cover or the back wall of the aquarium. For large aquariums with lots of fish install filter with a reserve power.
For creating extra flow and filtration in a large aquarium add an internal filter. If possible, do not skimp when you choose a filter, because it is the most important item of equipment in the aquarium.
