we are about to convert our chlorine pool to SWG. i use the poolcalculator and have figured how much salt to add. i am trying to find out the best way to check my salt from now on. i have the lamotte color Q photometer test kit. is there an electronic kit for salt? Or, are test strips good? I don't have a clue which way is going to be the best way to test my salt levels. what does everyone here use?
