Spa Alkalinity

The recommended total alkalinity level is 90 - 100ppm. The total alkalinity range should be in the range of 90 to 150ppm. To raise total alkalinity use Spa Pro Alkalinity Increaser in small quantities. To lower total alkalinity use Spa Pro pH Reducer which is a much safer alternative to Hydrochloric Acid.

For pH levels the recommended level is 7.2 – 7.6pH.  pH is measured on a scale of 1 to 14, with 7 being neutral.  A pH level below 7 means the water is acidic, and above 7 means the water is alkaline. Incorrect pH levels can cause poor chlorine or bromine efficiency, eye and skin irritations, corrosion of metal fittings, cloudy water and formation of scale on the spa's walls and fittings. pH should always be above 7 and measured at room temperature (not hot). It should never be allowed to get higher than 7.8. To increase pH add Spa Pro pH Increaser to lower pH use Spa Pro pH Reducer. After adjusting wait for one hour and then test again.
