The effectiveness of all sanitizers (chlorine or bromine) is effected when the pH level of the water increases. Ph reducer can be added directly to the hot tub water to reduce the pH to a desirable level. For the sanitizers to remain effective, the pH level should be kept below 7.6. However if the pH level drops too low then the water can start to degrade pumps and liners, so aim to keep the pH level between 7.2 and 7.6.
PH reducer is suitable for use in swimming pools, spas & hot tubs.
Reduces the pH level of the water to improve usage conditions.
1, Add 5g (1 teaspoons) to 1 litre of warm water and carefully add the solution to the spa whilst the pumps are turned on.
2, Check water balance level with a testing strip and add more Ph Minus if required.
3, Aim for a pH level of between 7.2 - 7.6.
