The white fog on the glass of the fish tank is a large number of dead nitrifying bacteria. This situation means that the nitrification system has collapsed, so the water quality will deteriorate rapidly and must be improved immediately. First of all, use the oxygen pump to explode oxygen in the water, and then change the water every two days, about one third of each time, until the water in the fish tank is completely clear.
1. Adding organic matter: If you want to cultivate nitrifying bacteria, the first step is to add organic matter to the tank. Generally, you choose fish food or shrimp segments. The purpose of adding them is to let microorganisms decompose them and produce ammonia nitrogen, which is the raw material of nitrifying bacteria. In this process, the water quality will gradually become turbid.
2. Nitrifying bacteria: Generally, nitrifying bacteria are poured into the jar together with organic matter. This kind of bacteria is divided into two types, one is nitrite bacteria that converts ammonia nitrogen into nitrite, and the other is nitrate bacteria that converts nitrite into nitrate. Both of them are indispensable.
3. Turn off the light to explode oxygen: Nitrifying bacteria are aerobic bacteria, and will be affected by light to cause death. Therefore, when cultivating bacteria, turn off the light to explode oxygen. Generally, after 48 hours of exploding oxygen, the water quality will change from turbid to clear. At this time, it means that the nitrification system has been established.
