FritzZyme® 7 Nitrifying Bacteria 473ML
FritzZyme® 7 contains live freshwater-specific strains of live nitrifying bacteria proven to reduce fish loss due to toxic levels of ammonia and nitrite. 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, faster addition of livestock.
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.
Why add nitrifying bacteria?
Nitrifying bacteria convert toxic ammonia into less harmful nitrite, and then into nitrate, which is safer for fish. This helps maintain stable water conditions and prevents sudden spikes in harmful substances that can lead to fish stress or death.

I added FritzZyme® 7 to my new tank after the first water change. The fish seemed more active and the water parameters stabilized within a week. No ammonia spikes since then. Great for new tank setups.

Used it after cleaning my filter and adding new fish. The tank stayed stable without any fish deaths. It’s a simple and effective way to support the nitrogen cycle.
Felicity James –
After a few weeks of using FritzZyme® 7, I noticed less fluctuation in nitrite levels. My fish are thriving and the tank feels more balanced. I’d recommend it to anyone starting a new aquarium.
