Use this Aquasparkle 1kg pack of Multifunctional Chlorine Tablets to disinfect and sanitise your hot tub / spa.
These tablets don’t dissolve instantly, but erode over time which helps maintain required chlorine levels for an extended time period.
These 20-gram chlorine tablets also have clarifiers that help achieve sparkling, crystal-clear water.
The tablets have a high pH value, so they don't cause acid damage to hot tub equipment or seals.
