Aquacal 75090, Owner'S Manual Installation And Operation

17

Example:

An 11,000 gallon pool with a salt level of 500-ppm

• The column value for 1000 gallons is 21 pounds

• The column value for 10,000 gallons is 209 pounds.

• The total of 230 pounds of salt is needed to reach pool salt level of 3000-ppm.

Salt Addition Chart:

To use this chart:

1

Find current salt level (ppm or g/l) in the left column.

2. Find pool/spa volume in the second row (Gallons or Liters).

3. Find the amount of salt needed to bring pool to the ideal level by finding the intersection of the

row and column.

REFERENCE SECTION

The salt is constantly recycled during normal operation. Loss of salt during a swimming season should
be minimal. Filter backwashing, draining due to rain water overflow, splashing and bathing suit drag out,
and leaks (excessive salt loss in a short span of time) are typical ways salt is lost. Salt does not leave
the pool when water evaporates.
