Note: If Soda Ash or Alkalinity Increaser has
recently been added ( 24 hours ) it is best not to add Calcium
Hardness Increaser until the next day. An insoluble precipitate is
likely to form resulting in cloudy water.
Caution:
DO NOT PRE-DISSOLVE IN A BUCKET OR ADD TO A SMALL QUANTITY OF WATER.
Heat is generated when this product is dissolved in water.
Directions:
Determine current calcium hardness level.
From the chart below, determine the quantity of Calcium Hardness
Increaser required to bring pool up to proper levels. As a general
rule, 6 pounds of Calcium Hardness Increaser per 10,000 gallons of
pool water will raise the hardness ( calcium ) level by 50 ppm.
For plaster pools, ideal hardness levels should be maintained
between 225-300 ppm.
For vinyl, fiberglass and non-masonry pools, ideal levels should
be between 175-225 ppm
Add Calcium Hardness Increaser directly to the pool water by
scattering over a large area.
Make certain that the circulation filter pump is operating.
