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 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!

Good

Works really well as a chlorinator but the algae killer in it does not seem to work real well, still have to use a algaecide in it to keep from getting algae

Love it in our smaller pool

Slow dissolving and no chlorine smell. This particular product we used in our smaller pool. It was safe enough for our pets which I loved. I hated their pool water sitting untreated and stagnant and these have eliminated that problem.

Works really great!

This product is great and so easy to use. Since it’s in granulated form I can add just the right amount to keep my pool at the correct levels. Seems to also work longer than others I’ve tried.

Works wonders

Great product to help maintain your pool. I load my floating duck with these tablets, toss it in the pool and have no worries about a clean pool. My mother uses off brand chlorine and ends up with green algae all the time. I use the products with the algae killing crystals and have never had any issues with algae at all. I highly recommend Clorox pool products with the algae killing crystals.

I found that the 1″ tablets dissolved sooner than the 3″ but like that I can use them in a smaller chlorine floater.

Xtra Blue Tablets

Even though I have a salt pool, my online review of products suggested that not only is it OK to use tables in a salt pool but this will help control algae and prevent corrosion. Well believe me it works!!! I am now getting compliments on how smooth and silky their skin is. I got to say mine is too.

Even with a salt pool chlorine is needed occasionally to keep levels up. I like the larger tablets versus the 1 inch.
