25 lb 3" Chlorinated Tabs Unwrapped Pail
Product Overview
A proven choice for maintaining consistent sanitization levels in residential pools using automatic feeders or floaters.
This 25 lb pail of Regal 3-inch tablets contains Trichloro-s-triazinetrione at a 99.0% concentration, providing 90% available chlorine. In our experience, these slow-dissolving tablets are the standard specification for homeowners who need a stabilized sanitizer that resists UV degradation. These 25 LBS of unwrapped tabs reliably handle the daily chlorine demand without requiring the constant manual dosing associated with liquid or granular alternatives.
Benefits & What Makes It Different
90% Available Chlorine
The high concentration of Trichloro-s-triazinetrione ensures efficient bacteria and algae control with less product waste compared to lower-grade alternatives.
Built-in UV Protection
The stabilized formula prevents sunlight from burning off chlorine, which is essential for pools in hot climates where UV rays can deplete unstabilized chlorine in hours.
Slow-Dissolving Design
Engineered specifically for use in skimmers or automatic chlorinators to provide a steady, controlled release of sanitizer over several days.
Product Details
Trichloro-s-triazinetrione 99.0%
1-3 tablets per 10,000 gallons per week to maintain 1-4 ppm chlorine residual.
Compatibility
- Do not mix with Calcium Hypochlorite or any other pool chemicals in the same feeder
- Wait until chlorine levels drop below 4.0 ppm before swimming
- Keep away from organic materials, acids, or moisture to prevent dangerous chemical reactions
When To Use This
Pro Tip
Always check your Cyanuric Acid (CYA) levels every few months; because these tablets add stabilizer with every dose, you may eventually need to drain and refill some water to keep levels within the ideal 30-50 ppm range.
Common Questions & Instructions
How many 3-inch chlorine tablets should I add to my 10,000-gallon pool?
For a typical 10,000-gallon pool, we recommend starting with 1 to 3 tablets per week in a feeder or floater to maintain a consistent 1-4 ppm chlorine residual, depending on bather load.
Do these Regal tablets contain cyanuric acid or stabilizer?
Yes, these tablets are made of Trichloro-s-triazinetrione (99.0%), which includes stabilizer (CYA) to protect the chlorine from being destroyed by the sun's UV rays, making them ideal for outdoor pools.
Can I put these 3-inch tablets directly into my pool skimmer basket?
While common, we recommend using an automatic chlorinator or floater to prevent high chlorine concentrations from potentially damaging your skimmer plastic or pump seals when the pump is not running.
