Maintain proper water chemistry (pH 7.2–7.6, Total Alkalinity 80–120 ppm, Calcium Hardness 25–75 ppm, Salt Level 1500–1750 ppm) using standard test strips. Improperly balanced water or low salt levels can cause system error codes, premature cell scaling, or inadequate bacterial sanitization leading to skin rash risks. Turn off spa power before inserting or removing salt cartridges from the housing tube.
