Hi there. lately my ph reading is varying a lot. I tryed to calibrate it, but it continues like crazy.
I did not include anything new at the system, and my code is the same at least for an month.
any idea whats going on?
One second it reads 6.4. In the next second it reads 5.6.. than 6.8 and keeps going...

Re: Crazy PH reading
Could be loose connection where the pH probe plugs in, stray voltage in the tank, or a failing probe.

Failing probe I think. How old is it? Take a cup of tank water and put the probe in it. Any difference?
