Review on 🐟 API Proper pH 7.5 Freshwater Aquarium Water pH Stabilizer - 9.2 oz Container, Proper pH 7.5 Powder JAR - Small by Sandra Johnson

My tank is 110 gallons. The instructions on the bottle say 20 teaspoons of this product for an aquarium of this size. I only use 5 teaspoons. The picture shows what my aquarium looks like 24 hours after adding this product to my aquarium. That's even after a 25% water change. The entire inside of the tank is covered with a white film of flour. Plants, driftwood, glass, everything is covered with it. I don't know if any of my fish died because I hardly ever see any of my fish. I don't know how long it will take to purify the water and clean the entire inner surface, but I am extremely dissatisfied and disappointed. Too bad I didn't read the reviews before buying. Now I see that many others had the same problem. I want my money back!
