the bottom filter fish tank feces? If there is feces in the bottom filter fish tank, it can be cleaned up when the water is changed, or it can be decomposed naturally. If you want to change the water and clean it, you need to prepare a pipe, put it to the bottom of the fish tank, and put the other end in a lower place, and then take a sip, the water will be pumped out from the bottom of the tank, and at the same time, it will carry the dirt in the fish tank. If it is to decompose naturally, it needs a strong nitrification system in the fish tank, which will not deteriorate the water quality after decomposition.
of the fish tank? 1. Physical filtration: The most important filtration in the fish tank is physical filtration. It is mainly responsible for the first layer of filter material, the most common is the filter cotton. Filter cotton can filter out impurities in water. It should be noted that in order to ensure the effect of filter cotton, it should be cleaned regularly. When cleaning, new water should not be used, and the original tank water must be used.
2. Chemical filtration: The function of chemical filtration is to adsorb ions in water. Commonly used are activated carbon, ammonia absorption stone, etc. They can be placed in the fish tank to achieve the effect of filtration. However, because there is a certain upper limit for adsorption, a batch should be replaced every three months or so, otherwise it will not be effective.
3. Biofiltration: Biofiltration is mainly used to culture nitrifying bacteria. Nitrifying bacteria can be poured in when the tank is opened, a little added every week, and at the same time, the lights should be turned off to explode oxygen, so that it can grow and reproduce faster, thus establishing a good nitrification system. Nitrifying bacteria can transform ammonia nitrogen to improve the water environment.
