Cal Upper

Cal Upper

Granular Water Hardness Regulator

The level of water hardness in pools is an important part of the overall operation of a swimming pool.  Lower levels of water hardness create aggressive corrosion and etching on under water masonry surfaces of pools.  This process leads to cloudy water and damage to filters.  CAL UPPER makes increasing water hardness quick and easy, thereby preventing damage to pools and improving water clarity.

Dilution: 10.5 lbs. per 10,000 gallons.
