GLB 5LB 1" Chlorine Tablets – Stabilized Pool Sanitizer
Reliable Chlorination Made Simple for Small Pools & Spas
When it comes to maintaining sparkling, safe water, chlorine tablets remain one of the most trusted solutions. The GLB 5LB 1" Chlorine Tablets are specifically designed for smaller pools, spas, and feeders that require consistent, controlled dosing without the bulk of larger tablets. Packaged in a convenient 5-pound pail, these stabilized, slow-dissolving tablets deliver dependable sanitation that protects swimmers and keeps water clear, all in an easy-to-handle size.
Whether you’re a homeowner managing a hot tub or a pool professional servicing multiple small bodies of water, GLB’s proven formula provides the balanced disinfection power you need.
Why Choose GLB 1-Inch Tablets Over Standard Chlorine?
Standard chlorine can be messy, inconsistent, and inconvenient, especially in smaller pools or spa systems. GLB solves this problem by offering pre-measured, compact tablets that:
-
Dissolve slowly and evenly for steady chlorine levels
-
Contain stabilizer (cyanuric acid) to protect chlorine from sun degradation
-
Minimize waste, odors, and handling risks
-
Work efficiently in floating chlorinators, feeders, or skimmers
For anyone tired of juggling powdered chlorine or oversized 3” tablets that don’t fit spa feeders, these 1” tablets are the perfect fit.

How They Work
Each 1” tablet contains stabilized trichloro-s-triazinetrione, the industry standard for reliable chlorination. Once placed in a feeder, skimmer, or floater, the tablet dissolves gradually, releasing chlorine at a steady rate. The stabilizer included in the formula ensures that chlorine remains active longer, even in outdoor pools exposed to direct sunlight.
By using these tablets, you maintain a consistent chlorine residual that protects against bacteria and algae without the peaks and valleys that can lead to cloudy water or unsafe swimming conditions.
Best Uses for GLB 1" Tablets
-
Spas & Hot Tubs – Keep water clear and safe in smaller volumes where 3” tablets are too strong.
-
Small Pools – Perfect for backyard plunge pools, wading pools, and above-ground systems.
-
Floating Chlorinators – Fits seamlessly into most floaters for hassle-free treatment.
-
Automatic Feeders – Designed to work with feeders that require 1” tablets.
Directions for Use
-
Test & Balance Water – Ensure pH and alkalinity are balanced before adding chlorine.
-
Add Tablets – Place 1” tablets in your chlorinator, feeder, or skimmer.
-
Monitor Levels – Aim for a free chlorine residual of 1–3 ppm in pools or 2–4 ppm in spas.
-
Adjust as Needed – Add tablets weekly or as water demand increases during heavy use or hot weather.
Always follow GLB’s instructions and never place tablets directly on pool surfaces, as this may cause staining.
Cost & Value Considerations
While liquid or granular chlorine can seem cheaper upfront, 1” tablets deliver predictable dosing and less waste. Their slow-dissolving nature means you add them less often, reducing the risk of over-chlorination or rapid depletion. For spas and small pools, they are far more efficient than cutting or breaking larger 3” tablets.
Over time, using stabilized tablets also saves money on chemical maintenance, since the stabilizer reduces the rate at which sunlight burns off chlorine.

FAQs About GLB 5LB 1" Chlorine Tablets

A: Yes. They contain stabilizer (cyanuric acid) to help chlorine last longer in sunlight.
Q: How long does a 5lb pail last?
A: Usage varies by pool size and frequency, but for spas and small pools, a 5lb pail can often last several weeks to months depending on demand.
