SpaGuard® Stain & Scale Control is a weekly treatment designed for spas to prevent scale buildup from high calcium and stains from dissolved metals like iron, copper, and manganese.

The formula bonds to metal ions and helps filter them out, reducing risk of cloudy water, surface damage, and equipment fouling.

Dosage is approximately 1 oz per 300 gallons of water weekly, making it simple to maintain preventive care.

Suitable for most spa sanitizing systems and easy to use: simply pour into water while the pump is running.

Regular use makes your filter more efficient, prolongs surface life, and gives clearer water for more enjoyable soak time.
