pH minus for lowering high pH
When pH is too high, use a product intended to lower it. Selection and dosing follow water testing and the maintenance method used for the pool or spa.
Granules for routine manual adjustment
AstralPool CTX-10 1.5 kg and GUAa POOL pH minus 1.4 kg are two options in the range. Choose pack size by consumption and dose according to the individual product label.
Liquid products and automatic dosing
An automatic dosing system needs a liquid product with a concentration and composition permitted by the equipment manufacturer. Technical-grade acids listed in the same category should not be treated as universal substitutes for pool pH minus.
After adjustment, allow the water to mix and retest pH at the interval specified in the instructions. Never mix acidic products with chlorine concentrates; contact can release hazardous gas.
