Langelier Saturation Index
A calculated number used to predict the calcium carbonate stability of
water. If the index is higher than +0.2, it can cause quick and excessive
calcium scaling on the salt cell. If the index is lower than -0.2, it can
cause the water to be corrosive and damaging to metals and minerals in
the water, such as the titanium inside the Cell.
Metals
Metals can cause the loss of chlorine. Also, metals can stain your pool
and tint your water. Have your local professional test and recommend
methods of removal.
Chloramines
Chloramines should not be present in pool water. When organic materials
are not fully oxidized by Free Chlorine, Chloramines are formed. This ties
up the Free Chlorine in your pool, and does not allow the chlorine in your
pool to disinfect. Chloramines also cloud pool water and burn the eyes.
Super Chlorinate (shock) to remove Chloramines at the initial startup of
the pool.
pH Levels
pH produced by the Electrolytic Cell is close to neutral pH. However,
other factors usually cause the pH of the pool water to rise. Therefore
the pH in a saltwater pool tends to stabilize at approximately 7.8. This is
within national standards. If the pool pH rises above 7.8, have a pool
professional test to see if other factors such as high Calcium Hardness or
Total Alkalinity are the cause, and then balance accordingly.
Total Dissolved Solids (TDS)
Adding salt to pool water will raise the TDS level. While this does not
adversely affect the pool water chemistry or clarity, the pool
professional testing for TDS must be made aware that salt has been
added. The individual performing the TDS test will then subtract the
salinity level to arrive at the correct TDS level.
