It is getting warmer here in SoCal, so I've been running the solar and the water is getting warmer. Today, my SWG showed the "check salt" light. I checked it and cleaned out a small amount of scale on the inside and gave it an acid wash, but it still reports the same.
It seems to be generating chlorine (I see the usual little bubbles).
Is this "normal". Is there anything I can or should do about it?
FC=3.5, CC=0, TA=80, pH = 7.4, temp = 73, CYA=70, CH=540
My water is naturally high in CH (about 220-240).
