Nitrifying bacteria will not cause fish to get sick, because the food of nitrifying bacteria is ammonia nitrogen in water.
Nitrifying bacteria is not a therapeutic drug, and there will be no problem if it is put too much. Nitrifying bacteria can regulate the water quality, keep the water in the fish tank in a good ecological environment and enhance the immunity of fish. It takes 10- 15 days a month, and water can be changed during this period, but it cannot exceed 1/5 at a time.

Matters needing attention in using nitrifying bacteria
1. In order to avoid killing water purification bacteria, remember not to use it with disinfection and sterilization drugs. If it is necessary to use bactericidal drugs or drugs to treat fish diseases, it will take at least one week before using water-purifying bacteria.
2. In the process of using water-purifying bacteria, it can be effectively controlled under the most suitable water temperature conditions, and of course its effect is also the most ideal. For example, photosynthetic bacteria can grow and reproduce normally in the range of 23-29℃. When the water temperature is lower than 23℃, their growth gradually stops, so the effect of using such bacteria in aquariums below 23℃ is poor.
3. In the process of using water-purifying bacteria, we must pay attention to the change of ph value of water quality. For example, nitrifying bacteria in fresh water have the best effect when the ph value is neutral, and the worst effect in acidic water. Therefore, if the water quality in the aquarium can be adjusted to neutral or weakly alkaline, its water purification effect will be better. Photosynthetic bacteria are most effective in water with ph of 8.2-8.6, so they are more suitable for seawater aquariums.
4. If you want to keep different water-purifying bacteria at the same time, you should pay attention to the * * * compatibility between bacteria. For example, nitrifying bacteria and photosynthetic bacteria are not suitable to be placed in the same aquarium at the same time, because they inhibit each other in the process of purifying water, which may reduce their purification effect.
