We have a new pool with a swg. We started the swg about two weeks ago and everything was great (pool temp was around 72). Now, the meter (Intellichlor) is indicating low salt. I added 30lbs yesterday and in the afternoon got a nice green light again. This a.m., I have the orange "need salt" light. The pool temp is 63 - could the low temp possibly be giving me a false "need salt" indication? Is there any correlation between pool water temperature and the accuracy of the meter on the SWG unit?
