Too much nitrifying bacteria will not harm fish. Nitrifying bacteria are beneficial bacteria and are not a drug, so they are not harmful to fish and will not cause fish death. The function of this bacteria is to convert ammonia nitrogen, which is produced after the decomposition of organic matter in the water. It can be poisonous to fish, but through the treatment of nitrifying bacteria, this substance will be converted into nitrates. But it should be noted that nitrifying bacteria must be put in first to establish the nitrification system, and then the fish are put into the fish tank. This step is very important, so the fish must not be put in first.

Tip:

When using nitrifying bacteria, be careful not to add too much, because too many nitrifying bacteria cannot be completely dissolved in the water, and when you add nitrifying bacteria, the water will temporarily become turbid. This is a normal phenomenon and is not allowed. The water needs to be changed. After a while, the water will become clear.
