The Process Of Nitrification In Aquaria - University Of Florida
Higher to a lower concentration, the fish is forced to retain an equal amount of ammonia to that which is present in the water. For example, if the water has 1.0-ppm ammonia, the fish will have to retain 1.0-ppm ammonia. Therefore, the fish is only able to release that little bit of ammonia above and beyond what is present in the water. ... Return Document
