Hi 
,
I am using a Polaris Watermatic feeding system for Chlorine and Muriatic Acid.
Lately when I get my PH reading and try to calibrate lower on the feeder it will not allow me to do so. I can only calibrate higher.
Anyone have any suggestions on what the problem might be? I am going to clean my sensor tips today in case that might have something to do with it.
TIA
