Your swimming pool water is cleaner & safer when your water chemistry is properly maintained.

Chlorine tablets are one of the key chemicals to maintaining your pool water, and 3 inch chlorine tablets are the most popular method of water sanitization among long-time pool owners. 3 inch tablets are thicker than other pool chlorine tablets, allowing them to dissolve slower and protect your pool water for longer. Moreover, 3 inch chlorine tablets are the ideal size for chlorine floaters or automatic chemical feeders.
