I took my water to get tested today and they told me that my salt levels were too high (4700) and I need to partially drain the pool, but my system is telling me that the salt level is 1400 (too low, add salt). Why would this be. Should I trust the people that tested it or my system, and is there a possibility my systems readings are wrong. If I need to partially drain the pool, how would I go about doing that?
