Use this 5kg Blue Horizons Multifunctional Chlorine Tablets 20g 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.

How to Use:

5kg Blue Horizons Multifunctional Chlorine Tablets 20g should be dosed via a floating dispenser.
When set up correctly your floating dispenser will dispense the correct amount of chlorine into the spa to maintain the ideal level between 3.0 to 5.0mg/l and all you need to do is top up the floating dispenser with new tablets as and when required.
This makes maintaining the sanitizer level in your spa very straightforward. When using a floating dispenser remember to remove it from the spa and place it on a non-bleachable surface while people are bathing.
