Review on Fritz Aquatics AFA83304 Fritzzyme 360 Freshwater by Laura Jenkins

I vacuum my 55 gallon aquarium once a week and do a 20% water change. In an attempt to keep maintenance to a minimum, I started adding a full cap of Fritz 360 Cleaner every two weeks. After three months of use, I noticed that the amount of waste removed from the gravel was reduced by at least 50%. The nitrate level remains stable at 30 ppm. A 32-ounce bottle should last a couple of years, so the cost is minimal. I keep it in the fridge. Please note that this is a live bacteria product. Exposing it to hot or frosty weather during transportation will greatly affect its viability.
