Spa Care Alkalinity & pH Increaser

Spa Care Alkalinity & pH Increaser - 500g

Increases Total Alkalinity and pH in spa and hot tub water. The lack of buffering that occurs if the Total Alkalinity is to low will cause the pH to fluctuate significantly. Water low in Total Alkalinity can also corrode equipment, etch some spa surfaces, cause skin and eye irritation in bathers and excessive chlorine usage.
