Spa Alkalinity Minus
Spa Alkalinity Minus is an alkalinity reducer for spas. Its fast acting and odourless formula 100% soluble does not influence total dissolved solids like regular granular formulas.
- If levels are high, add 60ml of SPA ALKALINITY MINUS per 1000 L of spa water to decrease pH of 0.4 and alkalinity of 14 ppm.
- Spa must be in operation before adding SPA ALKALINITY MINUS
- Wait 15 minutes and retest pH and alkalinity
- Repeat operation until recommended levels are reached
