For decades, world-class resorts, aquatic centers and leading swim venues have trusted calcium hypochlorite — cal hypo, as it’s known in our circles — as the gold standard for crystal-clear water with no CYA. The secret to the commercial pro’s success? Proprietary cal hypo briquettes and feed systems built for consistent, reliable performance. And up until now, professional-grade cal hypo briquettes have pretty much stayed in the hands of the pros.

PoolSense Smart Pool Technology from GLB changes all of that.
At the heart of the PoolSense system is a recyclable chlorinating cartridge loaded with cal hypo briquettes engineered through a proprietary process proven to deliver uniform hardness in every single briquette. That consistency is the foundation of reliable, predictable chlorination — cycle after cycle.
Cal hypo:
- Kills bacteria effectively
- Chlorinates without CYA (cyanuric acid), which means no chlorine lock — ever
- Protects pool surfaces and equipment compared to liquid chlorine and salt systems
- Delivers crystal-clear water with no waiting to swim
The PoolSense cal hypo chlorinating cartridge takes it even further:
- Zero direct chemical contact, fumes or spills
- Works optimally with the PoolSense Auto-Sensing, Auto-Dosing Smart Feeder, which continuously monitors water conditions and precisely doses chlorine and pH balancer 24/7
- Convenient and recyclable — and available exclusively through GLB, so every install you complete creates an ongoing service opportunity
And the best part? Just load the chlorinating cartridge and pH pouch and that’s it. Hands stay dry. Decks stay clean. Pool stays crystal clear — so your customers can get back to enjoying it.
