About This Item Low alkalinity levels in swimming pool water can cause undue damage to pool surfaces and equipment. HTH® Alkalinity Increaser 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 pool surfaces and equipment, like filter systems, and ensures healthy, comfortable swimming water by protecting against skin and eye irritation. HTH® Alkalinity Increaser is great for all pool types, including vinyl-lined pools and salt water systems. How to Use HTH® Alkalinity Increaser Use HTH® 6-Way Test Strips or Test Kit to test your water weekly and make sure the total alkalinity level is between 60 and 120 ppm. If alkalinity is below 60, add HTH® Alkalinity Up directly to the pool water to raise the alkalinity level and help keep pH levels in range.
