Smaller bodies of water require more controlled sanitation. GLB 1" Stabilized Chlorine Tablets are specifically designed for pools and spas where precise chlorine dosing is critical. These slow-dissolving tablets deliver consistent, measured chlorine release while protecting the sanitizer from rapid sunlight degradation.

Unlike larger 3-inch tablets that can overwhelm small systems, GLB 1-inch tablets allow finer control over free chlorine levels. This makes them ideal for spas, above-ground pools, splash pools, fountains, and inline or floating feeders designed for compact dosing.

Each tablet is stabilized with cyanuric acid to prevent UV burn-off, helping chlorine last longer and work more efficiently in outdoor environments. The result is cleaner, clearer water with fewer fluctuations and less frequent chemical adjustment.

GLB is a trusted name in professional pool care, and these tablets are widely used by service technicians who manage smaller water volumes that demand consistency and reliability.

Why 1-Inch Stabilized Tablets Are Important

Small pools and spas are more sensitive to chemical swings. Over-chlorination can lead to strong odors, eye irritation, and surface damage, while under-chlorination can allow bacteria and algae to develop quickly.

Using 1-inch tablets allows:

• Precise chlorine control

• Reduced risk of sanitizer spikes

• Better swimmer comfort

• More predictable water balance

Stabilization further ensures that chlorine remains active longer, even in direct sunlight.

Slow-Dissolving Formula for Controlled Dosing

GLB 1-inch tablets are formulated to dissolve gradually, releasing chlorine at a steady rate rather than all at once. This slow erosion helps maintain stable free chlorine levels and reduces the need for constant monitoring and adjustment.

When used properly in a floater or feeder designed for small tablets, they provide reliable day-to-day sanitation without overloading the system.

Ideal for Pools, Spas, and Specialty Applications

These tablets are commonly used in:

• Spas and hot tubs

• Above-ground pools

• Small residential pools

• Fountains and water features

• Inline or floating chlorinators designed for 1" tablets

Their size and dissolution rate make them unsuitable for large feeders designed for 3-inch tablets, but perfect for systems that require controlled, incremental sanitation.

Trusted GLB Quality

GLB manufactures pool chemicals to strict quality standards, ensuring consistent tablet size, density, and chlorine content. This consistency prevents feeder clogging, uneven dissolution, and erratic sanitizer delivery.

Professionals rely on GLB tablets for predictable performance and dependable water quality across a wide range of pool environments.

Proper Use and Handling

GLB 1" Chlorine Tablets should always be placed in an appropriate dispenser or feeder. Tablets should never be added directly to the pool or spa unless explicitly directed, as concentrated chlorine can damage surfaces and equipment.

Routine water testing is recommended to ensure chlorine and stabilizer levels remain within recommended ranges, especially in smaller water volumes where changes occur more quickly.

Why Consistent Sanitation Matters

• Controls bacteria and harmful microorganisms

• Prevents algae growth

• Maintains clear, safe water

• Reduces chemical fluctuations

• Protects pool and spa equipment

Precision sanitation is especially important in smaller systems.
