Spa Essentials Alkalinity Increaser provides spa owners with an effective way to raise spa alkalinity, which stabilizes a spas pH level. A stable pH level minimizes swimmer skin and eye irritation, helps improves water clarity, and prevents costly equipment damage from corrosion or scaling. Alkalinity Increaser's unique chemical composition enables users to enjoy their spa rather than worry about it.
1 1/2 oz per 250 gallons of water will raise alkalinity 25 ppm.
Add directly to spa water with pump and filter running.
