Clorox Pool&Spa Chlorine Stabilizer Pool Water Balancers Granules, 4 lbs for pH balancing

Clorox Pool&Spa Chlorine Stabilizer protects your pool's chlorine from the sun's harsh UV rays, so your chlorine lasts up to 12 times longer. Protecting your chlorine from burning off under the sun's ultraviolet rays with a chlorine stabilizer means longer lasting sanitization. Longer lasting sanitization means more splashes, more dives, and more pool fun! Chlorine Stabilizer is ideal for new pools, saltwater pools, and pools that use chlorinating liquid. Test your pool water every week to see if you need more pool stabilizer. Without checking regularly, the stabilizer levels may get too low, causing sunlight to degrade the chlorine you've applied. Lower chlorine levels make it easy for bacteria and algae to grow, so keep your chlorine stabilizer levels at the recommended ranges on the label. Our stabilizer now comes in a resealable bag. If you don't use it all at once, that's no problem. Simply seal up the bag and save the rest for later.
