The Better Alkalinity Decreaser Easy Acid is a safer and easier Total Alkalinity decreaser than liquid acid. This granular acidic salt reduces pool alkalinity with only mildly lowering pH. This is the perfect solution for when the total alkalinity is too high in pools, but there isn't a high pH. This eliminates most of the back and forth when balancing your pool. Safe and Easy It's not just more effective than liquid acid, it's also much safer. The granular salt is fast dissolving, making it safe for pool surfaces. Yet it's activated by water, making spills easy and fast to clean up. There's also no fumes, and no skin burns. It's also easy to use. Using generic test kits, just substitute the recommendation of every 1.5 cup of muriatic acid with one pound of Easy Acid (or about 10.5 lbs for 1 gallon of liquid acid).
