Leslie’s – 3 in Jumbo Chlorine Pool Tabs – 35 lbs Bucket

Not all tabs are created equal. We have the highest quality chlorine tablets available for controlling algae, bacteria, germs, and other microorganisms. For more than 50 years in the United States, we’ve produced and controlled our proprietary formula which is highly compressed into our tabs for a slower, more even dissolve rate — providing long-lasting sanitization.

Stabilized Chlorine

Our tabs consist of stabilized chlorine, meaning they are protected from the sun’s damaging UV rays. This ensures the chlorine continues to do its job in the water rather than breaking down when exposed to sunlight.

Controls Algae, Bacteria and other Germs

For cleaner and safer water, each tab contains the highest amount of available chlorine which provides consistent sanitization by controlling algae, bacteria, and other microorganisms.

Long-Lasting Tabs

We continue to control the entire manufacturing process of our proprietary formula which is densely compressed into our chlorine pucks for a slower, more even dissolve rate. You get superior, long-lasting, and more efficient tabs that provide proper chlorination.

No Fillers, Binders, or Glues

Ideal for chlorine floaters and automatic chemical feeders, our slow dissolving tabs are the highest quality and have absolutely no fillers, binders, glues, or additives like many others. These additives cause tabs to dissolve too rapidly and don’t provide a consistent distribution of chlorine. These fluctuating chlorine levels and inconsistent sanitization lead to quicker algae growth. Fillers, binders, glues, and other additives also increase the total dissolved solids in your water, which ultimately make the chemicals you use to maintain and treat your water less effective over time.

Strongest Available Chlorine Per Tab (90%)

Our Leslie’s chlorine tabs are safe for swimming water while containing the highest grade of trichlor chlorine sanitizer with 90% available chlorine to control bacteria, algae, and other contaminants.
