Why we love it
  • Effective pool chemistry management.
  • Easy to use and handle.
  • Long-lasting chlorine for pools.
Main Highlights
  • Stabilized for Consistent Chlorination: Formulated with a high percentage of available chlorine and built-in stabilizer, these 1-inch tablets help maintain steady sanitizer levels in small pools, spas, and feeders. Designed to resist rapid UV breakdown, they support dependable routine chlorination that keeps water clear, balanced, and swim-ready with less frequent dosing.
  • Slow-Dissolving Mini Tablets: Compact 1" tablets dissolve gradually to deliver a measured release of sanitizer over time. Ideal for floaters, small automatic feeders, and spa dispensers, they help reduce chlorine spikes while supporting even distribution throughout the water for consistent maintenance and fewer manual adjustments.
  • Ideal for Spas & Small Pools: The smaller tablet size makes them well-suited for hot tubs, above ground pools, plunge pools, and other systems requiring lower output chlorination. They fit easily into compact dispensers and are convenient for maintaining sanitizer levels in lower-volume water environments without over-treating.
  • UV-Protected Formula: Each tablet is stabilized to help protect chlorine from sunlight degradation, allowing sanitizer to last longer in outdoor conditions. Regular use helps control unwanted contaminants and maintain water clarity as part of a complete pool or spa care routine when used according to label directions.
  • Surface Compatible: Suitable for use in vinyl, fiberglass, tile, and gunite systems when dispensed properly through a feeder or floater. These tablets are intended for routine maintenance chlorination and integrate easily into existing water care programs that include testing, balancing, and filtration.
