What type of salt can I use?


There are a variety of different salts on the market that are safe to use in your pools and spas. They are marketed under multiple brand names.  What is most important, is knowing which ones NOT to use.  Also if you should choose to use one other than a “standard” salt how it will affect your pool or spa.

You should NOT use common table salt, rock salt and ice-melt as these contain anti-caking agents and other additives and impurities which can damage the electrode plates of the chlorinator, so avoid these.

Dead Sea Salt/Minerals are very popular with pools and spas for the mineral benefits they provide.  While they are fine to use, the minerals change the conductive properties of the water.  Why does this matter?  The power supply gauges the amount of salt in the water by the current passing through the cell assuming only salt is in the water.  The Dead Sea Minerals raise the conductive properties of the water allowing a higher current to pass through the cell.  This causes the Saltron Mini to think there is more salt in the water than there really is and it will light up the “High Salt” LED.  This causes a lot of owners to think their salt is too high when really their salt is too low or good.
