too much fish excrement in the fish tank? If there is too much fish excrement in the fish tank, you can clean it when you change the water. When changing the water, find a pipe, put one end of it to the bottom of the fish tank, the other end should be placed slightly lower than the bottom of the tank, and then suck it, through the siphon method to pump out the water, but also to bring out the fish excrement. In addition, fish excrement can also be completely handed over to the filtration system, allowing microorganisms to decompose and clean it.
of too much fish excrement? 1. Unbeautiful: The first problem to be faced with too much fish excrement is that it is not beautiful, especially if it is raised in a bare tank. There is no decoration at the bottom of the tank, and it is full of fish excrement, which looks dirty. If the bottom sand is laid, some light-colored bottom sand will easily expose the fish excrement, but the dark color can have the effect of concealing.
2. Water pollution: The main problem of fish excrement is water pollution. When it decomposes, it produces ammonia nitrogen, which is harmful to fish and gives off a fishy smell. To ensure the health of fish, a good nitrification system is needed to convert ammonia nitrogen into harmless nitrates.
3. Harm to fish: As mentioned above, ammonia nitrogen after the decomposition of fish excrement is harmful to the health of fish, and may even cause a large number of fish deaths. Therefore, in order to ensure the health of fish, it is necessary to clean up in time to improve the water environment.
