  • 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.

This has saved my tank from total failure

When I first started in the hobby, I didn't know what I was doing. Didn't fully understand the nitrogen cycle and how long it took to naturally cycle a tank. While this is a shortcut that you can use to quicken the nitrogen cycle, you will still need to do daily water changes if you stocked fish on day 1. If not, no amount of added bacteria is going to save your fish. Instead of weeks of waiting for the cycle to complete, this is more like days. Yes you will still need to do water changes on a non stocked tank, but at least the process doesn't take months on end.

An excellent start for a beginner!

It really helped me to start a new tank, who knows how long I would have been waiting for bacteria to grow otherwise. With this my tank was able to start growing a good stock of beneficial bacteria much quicker.
