Is the pool water looking a little green this week? Unlike rivers and lakes, which can flush out impurities on their own, pools need our help. That’s where chlorine tablets come in handy. These cupcake-sized doses of chemicals help maintain a clean pool without the need for daily water tests and constant adjustments. Here are the chlorine tablets we recommend.

In The Swim 3" Inch Pool Chlorine Tablets - 50 Pounds

Great for floaters

These 8-ounce units are wrapped in easy-to-open bags. In The Swim

These tablets are thicker than most, which allows them to dissolve slower and protect your pool longer. They’re also ideal for either chlorine floaters or automatic feeders. Be sure to test your pool’s chlorine level before adding tablets; usually, one or two tablets per week is sufficient for ideal sanitation.
