If your chlorinator is indicating “Check Salt” or “Low Salt” or “High Salt” don’t be alarmed. Unless you’ve lost a significant amount of water in your pool there’s a good chance you may need to clean your chlorinator cell. The chlorinator cells build up with scale here in Las Vegas given the high calcium deposits in the water.
DIY TIP: Cleaning your chlorinator cell is fairly easy, as long as you have the right tools. First, disconnect the chlorinator from the control box and then unscrew the chlorinator from the water line. Seal one end of the chlorinator. The typical pool store sells a cap for roughly $35.00. Once end is capped stand the chlorinator upright and fill with 24 oz. of fresh tap water. Now carefully pour 24 oz. of muratic acid into the chlorinator. You will see bubbles immediately form as the gas from the dissolved calcium deposits melts away from the cells. Once the mixture stops bubbling, pour out the liquid, unscrew the cap and wash the internal workings for roughly 20 seconds. Now attach the chlorinator and follow with connecting to the control box. Red Square Pools recommends the chlorinator be cleaned every 6 months as a regular maintenance.
NOTE: If your water is below 65 degrees Fahrenheit, chlorinators give false positive readings and do not produce chlorine. Be careful not proceed with adding salt haphazardly as this can lead to another project of partially draining the pool water and replacing with fresh water. As always, if you are uncomfortable with the maintenance of your pool or spa please consult a pool professional.
As always, pool owners should defer to the manufacturer of their salt cell for best practices in cleaning a salt cell / chlorinator. By all means, NEVER DIP your SALT CELL in a bucket of water or water/acid solution as this will VOID ALL WARRANTIES.
