Fi-Clor Spa Alkalinity Increaser 1.2 kg

Fi-Clor Spa Alkalinity Increaser corrects alkalinity when it falls below 80mg/l (ppm).

Alkalinity is a measure of the total amount of alkali in spa water. If the alkalinity is too low, most chemicals added to the spa will directly affect the water balance leading to rapid fluctuations in pH readings. Alkalinity at the correct level will help protect, or 'buffer' the pH.
