  • 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.

Great product to jump start the cycling

I recently moved my residence, and I had a well stocked 75 gallon aquarium which at over 600 lbs is impossible to move. I set up my spare 35 gallon tank in the new place and moved the fish into it. I purchased a new 75 gallon on sale and had it delivered to the new apartment. I installed the old filter, some of the old gravel and used Fritz Zyme 7 to help along the cycling. I rescued my livestock as soon as I could from the stress of overcrowding in the 35 and they were immediately happy in the new tank, as there was never a trace of ammonia or nitrite in their new home. I highly recommend this stuff.

Essential Product

This is my go-to when setting up a new tank. Since using it, I have had no issues getting a new tank going without any issues.
