Fritz Zyme 7 Live Bacteria (Freshwater)

This is a live bacteria that can be added to a newly established aquarium to speed up the cycling time. This isn't a magical cure all, but will speed up cycling time and water parameters should be monitored during. This 16oz bottle will treat 80 gallons of water for one dose initially. And 160 gallons for an established aquarium that just needs a boost in bacteria.

Directions & Dosage

For new systems, dose 4oz (½ cup) per 10 US gallons. For a large livestock system, new system dosage may be safely increased up to 10x.
For established systems after bacterial loss, use 2 oz (¼ cup) per 10 US gallons.

NOTE: Live product. Do not freeze or overheat. Store in a cool, dark place. Use before expiration date.

Fritz zyme 7

Haven’t had to use it yet. But aquarium co op has great prices and fast shipping and customer service is excellent

It really works well!

I kept some of my old aquarium water from another tank when I transferred my fish from a 25/29 gallon tank to a new 55 gallon tank. I still had the bacteria in the canister filter so I had to work fast. I added the rest of the new water treated with prime to the tank. Then I added several ounces of the Fritz Zyme to my tank. A week later and the water has been crystal clear except the initial 24 hours for the substrate to settle (It was new substrate). No ammonia spikes, and the water seems to have been perfectly fine. I have replanted my tank, and it seems that all the fish are healthy.

Cycled a new tank in no time!

I started out with a few small tanks before quickly setting up a 40 and 75 gallon tank.

While I could've cycled by wringing out dirty sponges, this product made sure it happened that much faster.

Love the way this stuff smells too!!
