  • 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 bacteria in a bottle. Adding it to your aquarium will help increase the beneficial bacteria count. In a new aquarium this helps in establishing the bacteria that breaks down fish waste, meaning you can add fish to your new aquarium sooner. In an established aquarium, it helps if you are adding additional fish or increasing the amount of food that you are feeding.

Do you already have an established aquarium? Fritz Zyme 7 can be helpful when adding new fish or livestock to your aquarium. Fritz Zyme 7 will also 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. Fritz Zyme 7 can also be used after you have changed water and finished medicating an aquarium to help reestablish beneficial bacteria.

Helped balance tank after move

Used this product after a big tear down and move due to a large water and substrate change. Fish and plants are doing really well, no losses. I am going to use this when I start my next tank.
