if nitrifying bacteria are put too much? Nitrifying bacteria will not cause fish to die. It has no direct effect on fish, but only converts ammonia nitrogen in water, which is harmful to fish itself, so it is helpful to their health. However, it should be noted that if the nitrification system in the tank is too strong and the nitrate content is relatively high, it will lead to a drop in pH, which is often referred to as acid drop.
of dead fish in fish tanks? 1. Poor water quality: Dead fish in fish tanks are usually related to water quality. On the one hand, it may be because the water quality is too poor. On the other hand, it may be because the water quality fluctuates greatly and the fish can not adapt to the death. Usually, in order to maintain the water quality, it is necessary to change the water regularly and have a filtration system.
2. Dissolved oxygen is too low: Fish breathe in the water. The dissolved oxygen in the water determines their health. Once hypoxia occurs, it will also lead to the death of fish. In order to avoid this kind of thing, we need to prepare an oxygen pump to oxygenate the fish tank 24 hours to ensure that the oxygen in the tank is sufficient.
3. Disease factors: If the fish is injured or sick, it will also cause its death. Usually, when it is found to be depressed and ulcerated on the body surface, it needs to be treated in time. First, it is necessary to change water, heat up and salt to see if the condition is alleviated. If there is no effect, it can be washed with medicine.
