Review on FritzZyme 9 Nitrifying Bacteria: Enhance Saltwater Aquariums with Fritz Aquatics by Amy Moultrie

I've been using this for a year and add it to my tank after every water change. It works great and does what it promises. While I didn't read the fine print on how much to use, I didn't use enough. 60 ml to 5 liters. I definitely didn't use enough, although it still worked with what I was using. Now with the right amount my SW tank looks even better and definitely helps keep it stable. A 25 gallon tank has its issues and the Zyme 9 helps make up for the lack of good bacteria my tank may need. I highly recommend using this as part of your water change routine. This won't let you down and it's used on New Panzer Syndrome tanks and established tanks, just make sure you add the right amount as directed for your intended target, it won't kill anything but too much of something can harm you coral. It is also convenient to use immediately after aquarium treatment and water change for quick recovery. I had cyanobacteria in my tank, I treated them for a few days, killed them, did a water change and then added Zyme 9 and my tank looked great the next day.
