If your pool struggles to hold chlorine—even when you’re adding it regularly—the issue often isn’t dosage, it’s protection. Sunlight rapidly breaks down unstabilized chlorine, forcing you to use more chemicals and making water balance harder to maintain. The GLB Stabilizer 4lb Pool Water Conditioner is designed to solve that problem by protecting chlorine from UV degradation and dramatically improving sanitizer efficiency.

Formulated with cyanuric acid, GLB Stabilizer acts as a chlorine shield, slowing down chlorine loss caused by direct sunlight. The result is more consistent sanitizer levels, reduced chemical waste, and better overall water balance—especially in outdoor pools.

Protects Chlorine from Sunlight and Rapid Burn-Off

In outdoor pools, UV rays can destroy a large percentage of free chlorine in just a few hours. Without stabilizer, pool owners are often stuck in a cycle of constantly adding chlorine just to keep up.

GLB Stabilizer bonds with free chlorine, protecting it from sunlight and allowing it to remain active longer. This protection helps:

• Reduce daily chlorine loss

• Maintain consistent sanitizer levels

• Improve chlorine efficiency

• Lower overall chemical consumption

It’s an essential product for any outdoor chlorine pool.

Improves Chlorine Efficiency and Water Stability

When chlorine levels swing too quickly, pools become harder to manage. Water can turn cloudy, algae can form, and chemical balance becomes unpredictable.

By maintaining proper cyanuric acid levels, GLB Stabilizer helps create a more stable chemical environment. Chlorine works more efficiently, adjustments become more predictable, and overall water quality improves.

This makes stabilizer especially valuable for:

• New pool startups

• Pools that won’t hold chlorine

• Pools exposed to full sun

• Seasonal openings and resets

4lb Size for Controlled, Accurate Dosing

The 4 lb container is ideal for residential pools, allowing pool owners to raise stabilizer levels gradually and accurately without overcorrecting.

Adding too much stabilizer can reduce chlorine effectiveness, so controlled dosing is critical. The manageable size helps ensure you reach the recommended stabilizer range without overshooting it.

Compatible with Most Chlorine Pool Systems

GLB Stabilizer is designed for chlorine pools, including:

• Liquid chlorine systems

• Granular chlorine programs

• Saltwater pools (when CYA levels are low)

It should not be used in pools that rely exclusively on non-chlorine sanitizers.
