Why Choose GLB 1" Chlorine Tablets?

Perfect for Small Pools, Spas & Inflatable Pools
These chlorine tablets for pool owners who want precise control are great for spas, kiddie pools, inflatable pools, and small above-ground setups. With a 1" diameter, you have more dosing options than with larger 3" tablets. This helps reduce waste and over-chlorination.

Slow-Dissolving for Continuous Disinfection
Each GLB tablet dissolves at a controlled rate, releasing chlorine steadily to keep water balanced and crystal clear. This reduces fluctuations in chlorine levels and helps prevent outbreaks of algae and bacteria.

UV-Stabilized for Lasting Protection
The active ingredient—Trichlor (Trichloro-s-triazinetrione)—is stabilized to resist degradation from UV rays. That means your chlorine works longer and more efficiently in outdoor pools and spas.
