1.2kg Quality Alkalinity Increaser
Raises the alkalinity of hot tub water
Fi-clor Hot Tub Alkalinity increaser should be used to raise the total alkalinity level in hot tub water. Alkalinity is a measure of the total amount of alkali in hot tub water. If the alkalinity is too low, most chemicals to the hot tub 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.
