Stain & Scale 16fl. oz

Keep your spa water clear and free from discoloration with Spa Ease Stain & Scale 1 pt. This powerful formula prevents your water from becoming rusty, brown, or cloudy by addressing impurities such as metallics (copper/iron) and salts caused by acidic water with low pH. Simply add Stain & Scale while filling up your spa, using it each time you refill your spa. For hot tubs up to 500 gallons, add 16 oz of product to maintain optimal water quality. Remember to clean your filter cartridges within 24 hours of adding the product for best results. If your spa has a high concentration of minerals or shows signs of scaling/rusty water, follow a constant maintenance program by adding 1 oz of product per 100 gallons of water weekly.
