Filter cotton is an important tool, which can be used to clean up impurities and ensure water quality in the process of fish farming. In the specific use, at least two layers of pads are needed. The top layer is the physical filter layer, which is used to block and filter some large particles in the fish tank. The lower layer can release other filter cotton such as biochemical cotton.
Sometimes the physical filter pads are thinner, and they tend to get dirty. Considering these two aspects, two layers of physical filter wool can be placed. Physical filter cotton needs to be cleaned regularly, and this interval is sometimes relatively short, especially in the case of dirty water quality. The two layers of physical filter cotton should not be cleaned together, and the other piece can be used when cleaning one piece, so as to avoid large changes in water quality and beneficial bacteria system in water. In addition, it should be noted that in the case of more fish in the fish tank, impurities will be more, at this time it is best to place more layers.
When placing filter cotton, some breeders will think that the more filter cotton they place, the better. In fact, this is a misunderstanding. This is not the case. There is no need to put too much filter cotton in the fish tank with reasonable breeding density. If placed too much, not only can not play their due role, but will cause some harm. For example, the number of layers of filter cotton in a relatively large number of cases, will hinder the flow of water. The greater the number of layers, the greater the effect on the flow. The filter cotton in the lower layer has no way to contact the water flow and impurities, which will cause unnecessary waste. If the quality of filter cotton is not very good, they will rot easily over time.
