How to use the filter in a small fish tank? What filter material is needed for filtration?

Small fish tanks generally use filters or filter barrels, which do not occupy the internal space of the fish tank and ensure that the fish have a place to move.

The advantage of the upper filter is that it is convenient to install and manage, but because it is above the fish tank, it may look uncoordinated and affect the overall ornamental.

The filter barrel is external and needs a special place to put it, but the filtering effect is still very good, but it is not convenient to clean.

First, how to use the filter of a small fish tank. A small fish tank generally uses a filter or a filter bucket, which does not occupy the internal space of the fish tank and ensures that the fish has a place to move.

The advantage of the upper filter is that it is convenient to install and manage, but because it is above the fish tank, it may look uncoordinated and affect the overall ornamental.

The filter barrel is external and needs a special place to put it, but the filtering effect is still very good, but it is not convenient to clean.

Second, what filter materials are needed for filtration? 1. filter cotton: filter cotton is an essential filter material in filtering equipment, which is usually placed on the first floor. Its function is very simple, filtering out the dirt and impurities in the water, so that the water flowing through will become clearer.

Moreover, some cotton filters can also cultivate nitrifying bacteria, thus playing the role of biological filtration.

2. Activated carbon: Activated carbon is usually the filter material in the second layer of filtration, which is mainly responsible for adsorbing various harmful ions, thus improving the water body.

It should be noted that activated carbon has an upper limit, and it is usually saturated in three months. At this time, it needs to be taken out and replaced, otherwise the absorbed ions may be released.

3. Fungus room: Fungus room is the place to cultivate nitrifying bacteria and the last line of defense for filtration.

Nitrifying bacteria can transform ammonia nitrogen in water. These substances come from decomposed fish food and feces, which are toxic to fish and can be converted into nitrate, thus providing nutrition for aquatic plants.
