By type of filtering

Mechanical

During mechanical filtration, water passes through a special filler, in which particles of debris remain in the pores of a sponge or fine mesh. The instructions for the device indicate the frequency of change of the filter element.

Chemical

Chemical filtration is based on the purification of water with the help of activated carbon, which has special properties that help clean the liquid from nitrates, ammonia and other harmful impurities. This method is effective, but it is worth being careful. After a few days, it is necessary to change the filter, since the excessive accumulation of chemical elements in it leads to their backward release into the tank.

Biological

Biological filtration is performed by special bacteria in the soil. Fillers are purchased, on which colonies of beneficial microorganisms are formed. They purify water from toxins and other harmful impurities.

It will also help bring a large amount of oxygen to the tank. For water purification apparatus of various capacities and dimensions are used. Depends on the volume of the tank.
