Effects on Biological Filtration
Nitrobacter and Nitrosomonas are widely recognized as the primary beneficial bacteria present in the biological filtration system of every aquarium. Some drugs, which treat fish disease are harmful to these "good" bacteria. When the biological filter is upset, there is a build-up of ammonia and nitrite concentrations, resulting in fish distress and sometimes 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.

NOTE: In heavily stocked aquariums, it is important to actively monitor ammonia and nitrite levels because during treatment, fish may excrete more waste materials. After treatment, it is always beneficial to add a boost to the biological filter with the use of a bacterial additive.
