1 meter 5 fish tank generally use 25W water pump, of course, the power of the pump is only one aspect, mainly depends on the size of the fish tank, so good to determine the flow of water. Usually this kind of tank needs 5000-6500 flow pump to ensure that the water body can be filtered 3-4 times in an hour, so as to maintain the water quality, otherwise the deterioration rate of the water body will be very fast.
1. Timely oxygenation: If the fish in the fish tank is found to be anoxic, the first thing to do is to timely oxygenate. This requires a special oxygen pump, which can be opened for 2-4 hours a day, 2 hours more in rainy weather, and 1 hour more in the evening if there are aquatic plants, so as to make up for the lack of oxygen.
2. Regular water change: In addition to oxygenation, water change can also play a role in supplementing oxygen. Because the oxygen content of new water is relatively high, and the process of adding water can also bring some gas into it. Usually the cycle of water change is 1-2 weeks, if there is filtration, it can be changed half a month, otherwise it will be changed once a week.
3. Reduce the density: The lack of oxygen in the fish tank is mainly due to the large number of fish. If the tank itself is not large, the oxygen consumption of the fish is high, and the phenomenon of lack of oxygen will naturally occur. To completely solve this problem, the best way is to reduce the breeding density, or change to a larger water tank.
4. Reduce feeding: If too much bait is fed at ordinary times, the fish will eat more and consume more oxygen. By reducing feeding, the occurrence of anoxia and other conditions can be effectively curbed.
