Chlorine for Pools

Pool chlorine tablets are designed to maintain chlorine residual for proper sanitization of the water. Known to be powerful, effective, and relatively inexpensive, chlorine tablets are the most commonly used primary sanitizer on the market. Chlorine tablets dissolve evenly and kill viruses, bacteria, and control algae, making them one of the easiest and most effective methods available.

Chlorine Tablets are designed to slowly dissolve for even chlorine distribution. Chlorine is the most popular form of sanitization for above and in-ground pools. Stabilized chlorine tablets are densely compressed to give them a longer life and provide an even distribution throughout the pool water. 3 Inch Chlorine Tablets are ideal for use in an automatic chemical feeder or floating chlorine dispenser. Each tab is individually wrapped for safety and easy handling.

Leslie's Chlorine Tabs

At Leslie's, we offer the industry's strongest and longest-lasting chlorine tablets on the market. With over 50 years of chlorine production in the United States, we’ve controlled our proprietary formula of highly-compressed tabs for a slower, more even dissolve rate compared to other tabs.

At Leslie’s, we manufacture our own chlorine tablets from start to finish to ensure the highest quality product. The process starts by adding first-rate pure trichlor into a large machine hopper, which then drops into a pressing machine. This high-pressure machine will then press the trichlor into densely compacted tablets. We have perfected the amount of time and pressure required to create the longest-lasting, slowest-dissolving chlorine tablets on the market.

At Leslie’s Pool Supplies, we only carry the highest quality chlorinating tablets for pools so you know you’re getting an exceptional product for your swimming pool. When you buy chlorine tablets from us, they’ll provide your water with an even and consistent amount of chlorine to keep your pool and spa properly sanitized.
