Water high in pH can corrode equipment, cause scale formation and metal staining, irritate skin and eyes of bathers and reduce the killing ability of chlorine over algae and bacteria.
GENERAL INSTRUCTIONS pH should be maintained in the range of 7.2 – 7.6. Total Alkalinity should be maintained between 125ppm – 150ppm. Ensure spa water is tested prior to adding pH & Alkalinity Reducer. DO NOTadd more than 25 grams of Alkalinity & pH Reducer per 1000 Litres of water at any one time.
TOTAL ALKALINITY INSTRUCTIONS & DOSAGE: Add 24gm of pH & Alkalinity Reducer per 1000 litres of water to lower Total Alkalinity by 10 parts per million (ppm)
DIRECTIONS FOR USE: calculate the required amount of pH & Alkalinity Reducer (see dosage above). Dissolve in a bucket of water, then poor slowly into the water with the pump and filter operating. Circulate water for 3 hours and then re-check with a test and repeat if necessary.
