FritzZyme® MONSTER 360 is a powerful, concentrated probiotic blend of naturally occurring, environmentally friendly, live heterotrophic bacteria capable of digesting organic sludge common in aquariums. FritzZyme® MONSTER 360 has been specially formulated to handle the organic waste produced by “monster” fish, including oscars, arowana, freshwater stingrays, piranha, peacock bass, arapaima, gar, etc., as well as heavily-stocked tanks (African cichlids). Sludge includes fish waste, leftover food and other decaying organic matter. Using FritzZyme® MONSTER 360 as part of a regular maintenance program will greatly reduce aquarium care including gravel vacuuming and water changes, as well as prolonging filter media life. The bacteria in FritzZyme® MONSTER 360 is safe, non-toxic and non-pathogenic.
