Fritz Zyme 7 is a bottled live bacteria that can be added to a newly established aquarium to speed up the cycling process. Beneficial bacteria are essential to a healthy aquarium and should always be present before adding livestock. We recommend testing your water often while using this product to ensure your cycle has successfully been completed.

The 8oz bottle will treat 40 gallons of water dosed when the tank is set up. It will treat up to 80 gallons for an established aquarium that just needs a boost in bacteria.
