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. Mother Nature doesn't have to gravel wash! Why should you? Fritz-Zyme™ #360 Gravel Cleaner removes all the organics - without disrupting the aquarium. This fast and easy way to clean your tank is safer than traditional siphoning. Removal of undesirable debris improves water quality & increases the level of dissolved oxygen in your tank. Since Fritz-Zyme™ #360 Gravel Cleaner is chemical-free, there is no danger in using it in fish, plant, or reef systems. Works great with undergravel filters, which tend to build-up large amounts of sludge underneath the plate. Reduces sludge build-up in your bio-filter that inhibits nitrifiers. Incorporating Fritz-Zyme™ #360 Gravel Cleaner into a regular maintenance program ensures the biological stability of your filter and re-creates the looks-like-new cleanliness every hobbyist dreams of. For best results, use once every 3 weeks or whenever visible sludge is present. Follow with Fritz-Zyme™ #7 in freshwater or Fritz-Zyme™ #9 in saltwater to maintain a healthy balance
