I had a problem with my return pump when I was out of town. I have a rkl with temp and ph probe. They both where dry for a little over 24 hours is this bad?
Temp probe is fine being dry...the ship from the factory dry.
pH probe should always be wet. I'd use some type of calibration solution to make sure its reading correctly. If not, try to calibrate. If all else fails, buy a new one
