This pH decreaser (sodium bisulphate, dry acid) quickly and effectively lowers both pH and total alkalinity levels in your spa. Bringing pH back into the ideal range of 7.2 to 7.8 helps protect your spa’s equipment and prevents skin and eye irritation for a more comfortable soak.
Application rate depends on your spa’s current pH and total alkalinity levels, so get in touch if you’re unsure of dosage.
