This product solved all my water quality issues. The fish in my 220 gallon tank had grown over the years to the point where I was having problems. I did not want to take any of my fish out of the tank because I was fond of them. I use the product weekly. My water is now crystal clear and i can keep all mey fish healthy. Fabulous product!
