  • Quickly establishes beneficial bacteria in new aquariums and speeds up the aquarium cycling process
  • Helps prevent fish loss
  • Fortifies beneficial bacteria in established aquariums

Fritz Zyme 7 is live beneficial bacteria in a bottle. Adding it to your aquarium will help increase the beneficial bacteria count. In a new aquarium, this helps to establish the  beneficial bacteria that breaks down fish waste, which means you can add fish to your new aquarium sooner.

In an established aquarium, FritzZyme 7 helps if you are adding additional fish or increasing the amount of food that you are feeding. It can help rebuild the beneficial bacteria population after a power outage, after you have done a deep cleaning (where beneficial bacteria can be disrupted during the cleaning process), and after you have changed filter cartridges or filters. It can also be used after you have changed water and finished medicating an aquarium to help reestablish beneficial bacteria.

Works every time.
Filter broke on 45 gal gold fish stock tank. Decided to get a bigger filter.
Purchased a fX2 used Fritz zyme 7. Zero problems.
Used Fritz zyme 7 to start and cycle the stock tank too.

Best bacteria

Fritz is the only bacteria that I use to start new tanks. Cycles all of my tanks very well especially if you can't wait to add livestock.

So good

My 75 gallon tank finally cycled and was really murky (white). This stuff cleared it back up in a couple of days! I did a water change/gravel vac and added more and now it is crystal clear.
