Hot tub shocking is easier with FROG Maintain non-chlorine shock. With a convenient single-dose pouch, hot tub users consistently add just the right amount — not too much and not too little. It dissolves rapidly; in 15 minutes, water is clean and crystal-clear, the company says. FROG Maintain is cyanuric acid free, ensuring no cyanuric acid buildup. Formulated to keep pH buffered, this product doesn’t affect the pH level either.
