Keeping smaller pools, spas, and specialty water features properly sanitized requires a chlorine solution that’s precise, consistent, and easy to control. GLB 1" Chlorine Tablets (5 lb container) are specifically formulated for applications where standard 3" tablets are simply too large or dissolve too slowly.

These stabilized, slow-dissolving chlorine tablets provide reliable daily sanitation while protecting chlorine from rapid UV degradation. The result is steady chlorine levels, cleaner water, and fewer swings that lead to algae growth, cloudy water, or strong chlorine odor.

This size and formulation make GLB 1" tablets a trusted choice for spas, hot tubs, small pools, fountains, and inline or floating dispensers designed for compact tablets.

Designed for Controlled, Consistent Chlorine Delivery

Unlike granular chlorine or liquid shock that can spike sanitizer levels, GLB 1" tablets dissolve gradually, releasing chlorine at a controlled rate. This helps maintain stable free chlorine levels while reducing the risk of over-chlorination.

Because these tablets are stabilized with cyanuric acid (CYA), they resist breakdown from sunlight—especially important for outdoor pools and exposed water features.

The compact 1" size gives you far better dosing control in smaller bodies of water where precision matters.

Why 1" Chlorine Tablets Matter

Many pool owners unknowingly over-sanitize small pools or spas using products designed for large residential pools. GLB 1" tablets solve that problem by delivering right-sized sanitation without constant adjustment.

Why It Matters

• Prevents chlorine spikes in spas and small pools

• Maintains steady sanitizer levels with less effort

• Reduces chlorine loss from sunlight

• Helps prevent algae and bacteria between service intervals

For service pros, these tablets also make routine maintenance faster and more predictable.

Ideal Applications for GLB 1" Tablets

GLB 1" Chlorine Tablets are formulated specifically for systems that require smaller, faster-responding sanitizer sources.

Best Uses

• Spas and hot tubs

• Small above-ground pools

• Fountains and water features

• Inline or floating dispensers designed for 1" tablets

• Supplemental sanitation in low-volume systems

They are not recommended as a primary sanitizer for large residential pools unless used in appropriately sized feeders.

Clean Water Without the Hassle

Because these tablets dissolve slowly and evenly, pool owners spend less time chasing chlorine readings and more time enjoying clean, clear water. The stabilized formula helps chlorine last longer, reducing how often tablets need to be replaced.

When used as directed, GLB 1" tablets help:

• Maintain consistent free chlorine

• Reduce algae growth

• Minimize odor and irritation

• Improve overall water clarity

Usage & Safety Notes

Always use chlorine tablets in a proper dispenser. Never place tablets directly into skimmers unless explicitly approved by the equipment manufacturer, as concentrated chlorine can damage plumbing and equipment.

Maintain proper water balance alongside tablet use to ensure chlorine performs effectively and safely.
