Notes from Mardel on biological filtration: "Nitrobacter and Nitrosomonas are recognized as the primary beneficial bacteria present in the biological filtration system of any aquarium.  Some drugs which treat fish diseases and parasitic infestations are harmful to these 'good' bacteria.  When the biological filter is upset, there is a buildup of ammonia and nitrite concentrations resulting in fish distress and death.  Mardel products have been tested with known strains of these bacteria with no adverse effects noted.  When used as directed, they do not interfere with the biological filter."
