Maintaining the correct salt level in your swimming pool is vital to maintaining adequate Chlorine levels in your water, and keeping a clean pool. Too little salt and your chlorinator may not produce any chlorine at all, or it may produce far too much and in the process damage the electrode.
Adding salt to your pool is easy, and can simply be added directly to the pool water. Once you’ve added your salt, ensure you broom it in making sure it’s all dissolved to avoid staining the surface, and to ensure any suction cleaner doesn’t suck up the salt.
1 bag of salt will raise an average sized pool’s salt levels by 500ppm.
Most swimming pool Chlorinators operate at a salt level somewhere between 3000 ppm and 7000ppm, however some Chlorinators can operate above 7000ppm, even safely up to 35000ppm (basically sea water) although you don’t necessarily have to maintain such high levels. For most Chlorinators though, salt levels should sit at or above 5000ppm.
The best practice is to learn the appropriate salt level specified by the manufacturer of your Chlorinator, test the salt level regularly and maintain your salt level accordingly, even aim for 500ppm higher than the recommended salt level to defend against small amounts of dilution and rain. For most Chlorinators, this wont hurt and will keep your cell in good shape.
