Pristine Check - 1lt
Add PristineCheck at a rate of 25ml per 1000 litres of water. Run your tub on the filtration cycle for 4 to 6 hours while PristineCheck sequesters the calcium out of the water and into the filter.
Test calcium hardness with a calcium hardness test kit.
When using the Pristine Blue system the calcium hardness of the spa water must be below 250ppm to ensure that the copper sanitizer can work effectively.
Clean filters thoroughly after use to remove scale using a powdered filter cleaner such as Splash Spas Spa Powder Filter Cleaner.
