Raises the Total Alkalinity of pool water. It is very important to monitor
Total Alkalinity as if it is too low, the water can become acidic and cause
damage to pool equipment and surfaces. Also helps to maintain the pH of
the pool at the proper level and prevents pH bounce.
Raises the Calcium Hardness of pool water. Especially important in plaster
or concrete pools, but also plays a key role in water balance in all pools.
Usually only required when fresh water is added. Prevents corrosion, pool
surface pitting, and foaming.
