PH- Pool Acid (Sodium Bisulphate)
Used to reduce the alkalinity of swimming pool and spa water, lowering the pH level.
Maintain a pH level of between 7.2 and 7.6 to ensure bather comfort and to prevent long term damage to the pool and equipment.
As a general guide add 100 grams to 10m3 of pool water.
Use a suitable test kit to establish actual requirements and adjust as necessary.
