Are More Fish Tank Filters Really Better?

Are more fish tank filters really better?

However, if you want to keep a mix, keep a few pieces of each, and then come with a group of matching fish. It is very dense and then there is no way. However, only by adding multi - layer Filter Cotton to hinder the water flow rate and impurities, the biochemical filtration will not be polluted by impurities. Otherwise biofiltration will become a decoration.

Everyone knows the theory of nitrifying bacteria. Therefore, when cleaning the filter, only the top filter is cleaned, but the lower filter may not be cleaned for a long time. If it is the ordinary filter cotton we purchased, the excess filter cotton in the lower layer will continue to accumulate debris, and eventually completely rot, resulting in the deterioration of the water quality of the Filter Media For Fish Tank.

The more layers of filter cotton, the more effective it is to block water flow because they are not as porous as biochemical filter materials. A large amount of filter cotton is clogged in the filter tank, which will seriously hinder the flow of water. If the time is too long, a lot of garbage and sedimentation area will form at the bottom. Much of the fishy smell in many aquariums comes from too much filter cotton.
When the impurities on the filter cotton are deposited to a certain extent, the direction of water flow on the filter cotton will change. One is that they do not pass through the filter cotton, which makes the multi - layer filter cotton at the bottom have no filtering function at all. In other words, it is useless, and the filter cotton is a waste.
Finally, multiple layers of filter cotton can easily lead to clogging, which can lead to overflow of water flow, resulting in water overflow accidents. All of these are the disadvantages of over - filter cotton. Therefore, under normal circumstances, we only need to put about two or three layers of filter cotton in the fish tank filter media. That is to say, as long as the water flow in the fish tank can pass through the filter cotton, 80 % of the large particles of impurities can be effectively filtered out. In this way, it is absolutely sufficient for the physical filtration of the fish tank filter material, and we can place other biochemical filter materials in the saved space.
In short, it is useless to put more white cotton. Physical filtration in a fish tank requires quality, not quantity.
