Chlorine Tablets for Swimming 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 take pride in offering the industry's strongest and longest-lasting chlorine tablets. Our commitment to quality is backed by over 50 years of chlorine production experience in the United States. Throughout this time, we have meticulously refined our proprietary formula, resulting in highly-compressed tablets that dissolve slowly and evenly, outperforming other options on the market.

Our dedication to excellence is evident in our comprehensive approach to pool chlorine tablet manufacturing. We oversee every step of the production process, ensuring the highest quality product. We begin by sourcing premium-grade pure trichlor, which is then carefully added to a large machine hopper. From there, the trichlor is transferred to a high-pressure pressing machine, where it is transformed into densely compacted tablets. Through extensive research and development, we have determined the optimal time and pressure required to achieve the longest-lasting, slowest-dissolving chlorine tablets available. By maintaining complete control over our manufacturing process, we guarantee a superior product that consistently delivers exceptional results.

Leslie's Pool Supplies is your one-stop shop for premium chlorinating tablets designed to keep your pool and spa water sparkling clean and safe for use. Our high-quality chlorine tablets are formulated to dissolve slowly and steadily, providing a consistent release of chlorine that effectively eliminates bacteria, algae, and other contaminants..
