Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. FritzZyme 7 provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, immediate addition of livestock. Fritz Industries was the first company to pioneer commercial-scale cultivation of nitrifying bacteria and has remained one of only a few in the world with continuous production for over 30 years. FritzZyme 7 may be added to new tanks or established systems any time the biofilter needs fortification including: after water changes, aggressive cleaning, adding new livestock, medicating or changing filter media. FritzZyme 7 contains live freshwater-specific species of nitrifying bacteria. Review: Kept my fish alive when I might have lost them all. - Saved my fish tank. 300 guppies lived when their tank started to leak and they were thrown into a new tank with no preparation. Started to crash and this stuff saved it ( with a lot of water changes). Easy to use. Well worth what I paid. Highly recommend. Review: This is necessary for all fish tanks. - I’ve used this on my tanks and friends’ tanks with struggling eco systems, it is WORTH IT! Soon after adding it, you start seeing the micro organisms responsible for keeping your water clean and your filter working well. I would recommend this to any aquarist as a basic need.👍 ## Features - 🐟 Live Nitrifying Bacteria for Rapid Cycle: FritzZyme 7 Freshwater contains live, species-specific strains of nitrifying bacteria, proven to quickly reduce toxic ammonia and nitrite levels, significantly reducing fish loss and cycle time in new and established aquariums. - 🌊 Versatile and Easy-to-Use: Ideal for use in both fresh and brackish water systems, FritzZyme 7 is perfect for post-maintenance applications, after water changes, aggressive cleaning, adding new livestock, or when changing filter media, ensuring a stable and healthy aquatic environment. - 🙌 No Refrigeration Needed with One Year Shelf Life: This product is uniquely buffered for long-term stability, eliminating the need for refrigeration and offering a convenient one-year shelf life, making it a hassle-free solution for aquarium maintenance. - ⭐ Proven Success in Aquatic Care: With over 30 years of continuous production and development, Fritz Aquatics is a leader in the industry, delivering the highest quality, viable nitrifying bacteria.

It works excellent. **Q: So just got my gallon jug in... It has a slight odor to it but its pink in color, not dark or anything...is it still good?** A: Absolutely. I have used a lot of this stuff, and have received it in slightly brown colors all the ways to the pinkish color, and it always has an earthy odor to it. It always has worked for me. **Q: Will it work if I put it before adding ammonia to the tank?** A: Assume you're using the ammonia to cycle/start a new tank? Pure ammonia is not to be added if there will be fish in the tank, only when doing a fish-less cycle; the fish and their waste will supply the ammonia for the bacteria to grow and survive; be sure to keep testing the parameters of the water with a test kit; look up the nitrogen cycle **Q: Is it supposed to be pink/purple? Thank you.** A: I havent seen a purple color yet so far. Mine been a light to dark pink color. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Kept my fish alive when I might have lost them all. *by K***R on April 12, 2026* Saved my fish tank. 300 guppies lived when their tank started to leak and they were thrown into a new tank with no preparation.
