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.
Fill your feeder or floater with tablets and adjust output to bring chlorine to 1 – 4 ppm, test and refill as needed to maintain adequate sanitization. For skimmer application, add 1 tablet per 10,000 gallons to bring chlorine to 1 – 4 ppm, then add more tablets as needed to maintain adequate sanitization.
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!

Individual plastic wrapping
The individual plastic wrap on the chlorine tabs degradates leaving an environmentally unfriendly mess Good but why
Have been using this product and ones like it for years and they work great. My “why” is this … WHY are the tablets individually wrapped? The last three or four I have purchased have been like this …. what a pain to have to unwrap 10 per cycle of filling my auto feeder. AMAZING PRODUCT
FOR 40 YEARS i HAVE BEEN FIGHTING ALL THE MAGIC NUMBERS TO BALANCE MY POOL THIS YEAR WE BOUGHT THE ACTIVE 99 AT BJ’S FOR THE FIRST TIME AND MY POOL HAS BEEN CLEAR, NO ALGAE, NO SLIME JUST COOL CLEAR WATER . I HAVE NOT EVEN HAD TO BACK WASH AND I USUALLY HAVE TO CLEAN THE GRIDS ONCE OR TWICE A SUMMER; THIS YEAR…NOT YET AND WE CLOSE IN 4 WEEKS. I DO NOT KNOW OR CARE WHAT IS IN IT BUT IT IS NOW MY PREFERRED PRODUCT poor quqlity
Pool cloudy since I stared using Active 99. Tabblets were not wrapped and is overpowering when you open the container. Got a lot of rain and my pool turned completely dark green. Finally got that taken care of but still cannot get the cloudiness out. Had my water checked at a pool Pro and my water chemistry in fine. I firmly believe that the problem is Active 99. changing tablets today and I will know for sure.
