  • 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.

Easy to use

I just started cycling new tank with this. I haven't gotten the results yet, but it was easy to use and seems like a good value for the price.
