FritzZyme 9 Saltwater Live Bacteria
FritzZyme® 9 contains live saltwater-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® 9 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® 9 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?
- To quickly establish a stable biological filter in new aquariums
- To reduce the risk of ammonia and nitrite spikes during system changes
- To support safe fish additions after filter maintenance or cleaning

Robert Lewis –
I added FritzZyme 9 after cleaning my filter and noticed a significant drop in ammonia levels within 48 hours. My fish stayed healthy and I was able to add new fish without stress. Works well in a 55-gallon saltwater tank.
Ruth Skinner –
Used it after a major water change and filter replacement. The bacteria settled quickly and kept nitrite levels low. Not a magic fix, but a solid support for new tank setups.
James Newman –
Great product for reducing ammonia spikes. I’ve used it twice now—once after adding new fish and once after cleaning the filter. My tank has been stable since.
Bella Graham –
It’s effective when used at the right time. I don’t see immediate changes, but over a week the water parameters improved noticeably.
