SpaBoss Prevent II 32 fl. oz.

Prevent II is a Multi-purpose liquid concentrate which eliminates and prevents staining and scale formation in spas and hot tubs by preventing the escape of dissolved metals and minerals from the water. Regular use will enhance heater performance by eliminating scale build up. When opening the spa/hot tub, add Prevent II directly to the water at a rate of four ounces per 500 gallons. For weekly treatments, add at a rate of two ounces per 500 gallons of water to maintain the highest water clarity.
