Lower pH in the whirlpool – safe, effective and residue-free
A correctly adjusted pH level is the basis for pleasant, clear, and skin-friendly whirlpool water. If the pH level is above 7.6, the water can irritate skin and eyes, impair the effectiveness of disinfectants, and cause technical damage.
Delphin Spa pH-Minus Granules were specially developed to specifically and reliably reduce excessively high pH levels. They dissolve quickly and without residue and can be sprinkled directly into the whirlpool water – but it's better to pour them dissolved in a plastic bucket.
The recommended dosage is 10 g per 1,000 liters of water to lower the pH by 0.1. For example, if the measured pH is 7.8 and the target pH is 7.4, 40 g is needed. The pH should be checked again one day after addition and further adjusted if necessary.
