FROG® DropH™ pH & Total Alkalinity Decreaser (3 lb)
FROG® DropH™ is a premium granular pH reducer specifically formulated for hot tubs and spas. When your water's pH rises above the ideal range (7.2-7.8), it can cause cloudy water, scale buildup, and reduced sanitizer effectiveness. This 3-pound container provides multiple treatments to keep your spa water perfectly balanced, protecting both your equipment and your skin.
Unlike harsh liquid acids, FROG DropH uses a safer granular formula that dissolves quickly without splashing or fumes. It's compatible with all sanitizer systems including chlorine, bromine, and mineral purifiers, making it the perfect choice for any hot tub owner.
