Fritz FritzZyme 7 Freshwater Live Nitrifying Bacteria 8 fl oz

FritzZyme® 7 is formulated with live, freshwater-specific nitrifying bacteria that effectively minimize fish mortality caused by harmful ammonia and nitrite levels. In new aquariums, it can take several weeks for beneficial bacteria to colonize naturally, during which time ammonia and nitrite can spike to dangerous levels within days. FritzZyme® 7 delivers a balanced mix of bacteria that quickly establishes biofilters, significantly shortening the cycling process and enabling a safer, quicker introduction of fish. This product is ideal for both new setups and existing tanks whenever the biofilter requires reinforcement, such as after water changes, thorough cleaning, adding new fish, treating with medications, or replacing filter media.
