Uneaten food, fish waste and other organic nitrogen containing compounds are broken down by bacteria into ammonia and in a further step into toxic nitrite. This nitrite is further processed by other beneficial bacteria into nitrate, which in low concentrations is not dangerous. In a well-functioning aquarium or pond the nitrate value should be less than 20 mg/L. Especially in the initial or start-up phase of the aquarium or pond the filter bacteria are not been developed well and so regular monitoring is very important to avoid ammonia or nitrite toxicity to animals.
Keep out of reach of children.
