Salt may take 24 - 48 hours to dissolve in summer, and longer in
winter. Finer granules of salt will dissolve faster than compressed
pellets.
Water Softener salt (also known as Water Conditioning pellets) is an
economical way to buy large quantities of salt. However, only salt
that is at least 99% pure NaCl can be used. Pellets are compressed
forms of evaporated salt that may take longer to dissolve. Avoid using
salt with anti-caking agents (Sodium Ferrocyanide, also known as YPS
or Yellow Prussiate of Soda) that could cause discoloration of fittings
and surface finishes in pool. Do not use Calcium Chloride as a source
of salt. Do not use Rock Salt; insoluble impurities mixed with the rock
salt can shorten the life of the unit.
The CircuPoolRJ Series can work within a broad salinity range, from a
minimum of 3000 ppm (parts per million), up to 4000 ppm. However,
the ideal level for operation is about 3500 ppm. To achieve this level
of salinity, add approximately 30 lbs of salt for every 1000 gallons of
water (or 3.6 Kilograms of salt for every 1000 Litres). If you are unsure
of the number of gallons in your pool, double-check with the
equations below.
Gallons (Measurements in Feet)
Rectangular - Length x Width x Average Depth x 7.5
Round - Diameter x Diameter x Average Depth x 5.9
Oval - Length x Width x Average Depth x 6.7
Before adding salt, check your water for any existing salt content and
add according to the chart below. If too little salt is added, the result
will be reduced efficiency and a low level of chlorine production. In
addition, operation at low salt levels will reduce the longevity of the
cell. The salt in your pool is constantly recycled, and the loss of salt
throughout the swimming season should be small. This loss is due
primarily to the addition of extra water to replace water lost from
splashing, backwashing, and draining. Salt is not lost due to
evaporation.
