Doheny's 3 in Chlorine Tabs, 25 lb

For over 50 years, Doheny’s has been a trusted name in the pool supply industry, delivering top-quality products that keep pools clean, safe, and enjoyable. Our Pro-Grade Chlorine Tablets offer hassle-free pool sanitation, ensuring crystal-clear water without the guesswork.

Engineered with a highly compressed, dense formula, these tablets dissolve slowly, releasing chlorine at a controlled rate for longer-lasting effectiveness. Unlike other tablets that dissolve too quickly—wasting chlorine and requiring frequent dosing—Doheny’s chlorine tabs maximize efficiency while keeping your water balanced.

Each tablet is pre-stabilized against harmful UV rays, preventing premature chlorine burn-off and ensuring consistent disinfection. This means you get more use out of each tablet, reducing the need for frequent replacements and saving you money. Plus, our individually wrapped design minimizes odor, dust, and skin contact, making handling safer and easier.

Designed for all pool types—including chlorine pools, saltwater pools, and spas—Doheny’s slow-dissolving chlorine tablets provide reliable protection against algae, bacteria, and contaminants. Experience superior pool care with Doheny’s—trusted by pool owners for over half a century.
