Fritz-Zyme 360 Sludge Remover

Fritz-Zyme™ #360 Gravel Cleaner is the safe, non-chemical method of quickly and permanently removing "mess" from your aquarium. The sludge you see and smell is a mixture of precipitated organics. This consists of fats, starches and cellulose that can NOT be broken down by the nitrifying bacteria that you work so hard to cultivate in your filter. Fritz-Zyme™ #360 Gravel Cleaner contains a special blend of billions of bacteria & enzymes to rapidly break down waste, leaving your tank looking like new again. These bacteria are naturally occurring in rivers, lakes and streams.
