Maintain a Clean Pool

Your pool chemistry can change quickly. Test your pool water weekly to ensure your Free Chlorine level remains between 1 – 4 ppm. If needed, apply the appropriate chlorine or sanitizer to restore adequate sanitizer levels.

Maintain a regular cleaning regimen. Skim water surface, brush walls, vacuum and empty skimmer baskets at least once per week. Download the Clorox® Pool app on the Apple App Store or Google Play for expert water analysis and product and dosage recommendations.

This season, spend less time maintaining and more time enjoying your swimming pool!

So Easy to Use

We used the XtraBlue chlorination granules this year to shock and sanitize our pool water after a long winter. It’s amazing how clear our water is and how clean the pool is. The granules are super easy to use and dissolve quickly so we don’t have to worry about our liner. The granules also help to prevent all types of algae. This is a definite plus. Also, this product makes our pool water feels silky unlike some chlorine granules we had used in the past.
