Increases chlorine levels, kills and prevents bacteria and algae, reduces eye and skin irritation, prevents stains from metals, prevents scale, improves filtration, and softens water all with results in 24 hours.

The fast-acting, fast-dissolving Cal Hypo based formula provides chlorination without adding extra CYA for a beautiful sparkle all season. Its ideal for all pool surfaces and will not fade your liner
