These Blue Horizons Small Chlorine Tablets (20g) are designed for use with skimmers, chlorine feeders or with floating dispensers.
Blue Horizons Small Chlorine Tablets (20g) will typically slowly erode over a period of 3 - 5 days, depending on the water flow rate over them.
As they release chlorine relatively slowly (compared to chlorine granules) it may be necessary to shock dose or oxidise prior to their use to first establish chlorine levels more rapidly.
How to Use:
Blue Horizons Small 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. While people are bathing remember to remove the floating dispenser from the spa and place it on a non-bleachable surface
