HTH Pool Care Chlorine Stabilizer — Granules, 4 lb — Pool Chemical Stabilizer for Sunlight Protection

Over time, sunlight exposure affects the chlorine in swimming pool water, causing it to work less efficiently. HTH® Pool Care Chlorine Stabilizer helps protect and extend the life of chlorine in your swimming pool so it stays more effective for longer. If you're using an unstabilized chlorinator, adding stabilizer separately can help slow down the effects of direct sunlight on the chlorine levels in your pool. HTH® Pool Care Chlorine Stabilizer is great for all pool types, including vinyl-lined pools and salt water pools.

How to Use HTH® Stabilizer Use HTH® 6-Way Test Strips or Test Kit to test your water weekly. If the stabilizer level is below 20 ppm, apply HTH® Chlorine Stabilizer directly to the skimmer for healthy swimming.
