Increases the total alkalinity of pool water; thus makes the maintenance of a stable pH much easier and prevents wide fluctuations during pH adjustments. Test the water with 6 in 1 test strips/5 in 1 test strips for the Alkalinity reading.


Recommended level for total alkalinity 80-200mg/litre. To increase total alkalinity by 10mg/litre (ppm) add 1.5kg per 100m³. Low alkalinity may result in damage to pool surface finishes or pool equipment.


Dissolve Alkalinity Plus in water, in a plastic bucket. Distribute evenly around the pool. Raise alkalinity gradually continuing treatment daily until correct levels are present.
