About This Item Low alkalinity levels in spa water can cause undue damage to surfaces and equipment. HTH Spa Alkalinity Up not only raises the total alkalinity in your pool water but it also helps keep the pH levels from fluctuating. This helps prolong the life of spa surfaces and equipment like filter systems and ensures healthy comfortable water by protecting against skin and eye irritation. HTH Spa Alkalinity Up is compatible with all sanitizers including bromine chlorine and biguanide. How To Use HTH Spa Alkalinity Up Use HTH Spa Test Strips to test your spa water.
