REGAL 4 lb Pool Stabilizer Pouch
Product Overview
A proven choice for shielding chlorine from UV degradation to prevent rapid sanitizer loss in sunny conditions.

This 4 LBS. container of 100.0% Cyanuric acid reliably handles the task of shielding your sanitizer, ensuring that your chlorine remains active for disinfection rather than being wasted by sunlight. In our experience, maintaining a proper stabilizer level is the most cost-effective way to reduce overall chemical consumption.

When To Use This
Pro Tip
In hot climates with high UV exposure, chlorine without stabilizer can dissipate in hours. Instead of pouring directly into the skimmer, place the 4 lb of granules in a mesh sock and hang it in front of a return jet to prevent the stabilizer from sitting in your filter.
Common Questions & Instructions
How much REGAL Pool Stabilizer do I need for a 10,000-gallon pool?
To raise your cyanuric acid levels by approximately 30 ppm, you should add roughly 2.5 lbs of this 100.0% stabilizer per 10,000 gallons of pool water to reach the ideal range.
Can I swim immediately after adding cyanuric acid stabilizer?
While the product is safe once dissolved, we recommend waiting at least 15 to 30 minutes for the granules to circulate through the filtration system before entering the water.
Does this product affect my pool's pH or alkalinity?
Cyanuric acid is mildly acidic; while it primarily raises stabilizer levels, adding large amounts at once may slightly lower your pH and total alkalinity, requiring a minor adjustment.
