2kg Alkalinity Up
Alkalinity Up (Buffer) acts as a buffer to help stabilize your pH. Alkalinity represents the number of bicarbonates, carbonates and hydroxides present in the water. If these are out of balance this changes the degree of resistance to changes in the pH.
If the alkalinity is not balanced correctly, chlorine added can be wasted. Chlorine relies heavily on pH and alkalinity being in the recommended ranges to work effectively.
