4lb Chlorine Stabilizer

Clorox Pool&Spa Chlorine Stabilizer protects your pool’s chlorine from the sun’s harsh UV rays so your chlorine lasts much longer. Protecting your chlorine from burning off with a chlorine stabilizer means longer lasting sanitization, so you don’t have to apply as much product to your pool. Chlorine Stabilizer is ideal for new pools, saltwater pools, and pools that use chlorinating liquid.
