xSpeed up a healthy aquarium cycle with FritzZyme 7
Fritz Aquatics offers FritzZyme 7 Live Nitrifying Bacteria for Freshwater in a convenient 1-gallon bottle. This product contains freshwater-specific strains designed to help establish a robust biofilter more quickly, supporting a stable environment for your fish and plants from day one. Instead of waiting for natural colonization to catch up, FritzZyme 7 provides a ready-to-work microbial balance that can help shorten the typical cycle time and reduce early stress for livestock.
What it does
In healthy biofilters, nitrifying bacteria convert toxic ammonia into nitrite and then nitrate, contributing to safer water chemistry. The freshwater-specific strains in FritzZyme 7 are formulated to support standard tanks and systems, and the product is buffered to remain stable without refrigeration, with a one-year shelf life for easy storage.
- Rapid cycle support: live nitrifying bacteria work to lower ammonia and nitrite, helping to reduce fish stress in new and established tanks.
- Versatile use: suitable for freshwater and brackish environments, including after water changes, aggressive cleaning, adding new livestock, or changing filter media.
- Convenient storage: no refrigeration needed and a one-year shelf life simplify planning and setup.
- Proven track record: Fritz Aquatics has more than 30 years of continuous production of viable nitrifying bacteria.
- Stability after disturbances: use FritzZyme 7 to reinforce the biofilter following maintenance or system changes.
How to use and best practices
Disperse FritzZyme 7 into the aquarium or dose according to directions to fortify the biofilter. It is suitable for new tanks or established systems and can be added after maintenance, when introducing new fish, or during medication or filter media changes. The product supports ongoing stability but does not guarantee outcomes, so pair it with consistent routine care.
