1. Can the bottom filter cotton be soaked in water?

It is better not to soak the bottom filter cotton in water, but to filter it by dry and wet separation. This requires that the filter cotton be raised out of the water surface, so that it is not easy to cause overflow and need not be cleaned frequently. The main function of filter cotton is physical filtration, that is, to leave all kinds of impurities in the filter tank, so that the water looks clearer, but the impurities should also be cleaned regularly to avoid blockage. What are the benefits

of

filtration? 1. Improve water quality: The primary role of filtration is to improve water quality. It is generally divided into two parts, the first is physical filtration, which can leave impurities in the water in the filter tank, so that the water becomes clear. The second is biological filtration, although it can not achieve immediate results, but it can convert invisible ammonia nitrogen in the water body, avoid fish poisoning, and also play a role in improving water quality.

2. Improve dissolved oxygen: Filtration can improve dissolved oxygen, but its effect is relatively limited. If there are not many fish and they are not large fish, it is no problem to rely on it to ensure the breathing of fish, but if they are large fish, it is better to prepare an oxygen pump for oxygenation.

3. Disease prevention: Another benefit of filtration is disease prevention, because the water keeps flowing and anaerobic bacteria are not easy to reproduce, thus reducing the possibility of illness. Of course, prevention does not mean 100% success, fish may still get sick, so we must do a good job of countermeasures.
