The newly bought bed sand needs to be disinfected first. Soak it in potassium permanganate solution for a period of time. In this way, bacteria can be eliminated. Then rinse it with clean water. Even if the residual medicine is washed away, it can be put into the fish tank. If it is still turbid in the cylinder, dust particles can be removed by strengthening filtration, and the water quality will gradually become clear.
1. Beautify the environment: If you raise fish in a naked tank, the fish's feces will fall to the bottom of the water, which naturally looks not very beautiful, and after laying the bottom sand, the feces will fall into the gap, so you can't see it. However, the feces falling into the gap also need to be cleaned up, otherwise too much accumulation will affect the water quality, usually when changing water, it can be discharged.
2. Stabilize water quality: bed sand can play a role in stabilizing water quality. Changes in water quality have a great impact on fish. Not only will it not eat, but it may also produce a stress reaction, or even cause its death. By laying the bottom sand, the hardness and Ph of the water body can be stabilized in a range, so that the growth of fish will be more healthy.
3. Provide hiding: For some fish, their courage is relatively small. If there is no shelter in the fish tank, the fish will often appear very uneasy, and the bottom sand can allow some fish to hide in it.
