With the development of the economy and the improvement of people's living standards, more and more people are raising fish. Fish farming can not only cultivate one's body, but also improve the quality of life. The lively fish also add a lot of vitality to the interior. Old players all know that fish farming is easy, but mastering is difficult. If you want healthy growth of fish, you must ensure good water quality. In order to multiply nitrifying bacteria, biological filtration is essential, so how should you choose these filter materials? Woolen cloth? Old players come to help.
The role of biological filtration is to provide a habitat for nitrifying bacteria, because nitrifying bacteria are an important part of the fish tank ecosystem. If the nitrifying system is not perfect, it is difficult for fish to grow healthily, and nitrifying bacteria need to be attached to certain objects. Therefore, the biological filter material has become an indispensable part of the fish tank. Biological filter materials include ceramic rings, biochemical rings, bacterial houses, glass balls, and coral sand.
The ceramic ring should be selected with large surface volume, porous and good water permeability. The surface of the bacteria house is porous and dense, and does not drop slag. When you buy it, blow it with your mouth, and the air flow will be better. Coral sand can adjust the ph value of water quality, and it is best to choose the surface with more pores and uniform color. The glass ring is made of stone powder, and the hole is relatively small, which can cultivate aerobic and anaerobic nitrifying bacteria. The biochemical ring is mostly used in trickle filtration, and its material is plastic.
The above is about the selection method of filter materials. I hope that the finishing of the editor will be helpful to you, and I hope that everyone can raise healthy and high-quality fish.
