Test Water Levels

When your pool is out of balance, your sanitizers can be less effective. Unbalanced water can also cause skin and eye irritation, and it can even damage the pool’s surfaces, structure or equipment. Use the HTH® 6-Way Test Strips to check alkalinity, pH and chlorine levels two to three times a week.
