Ph probe calibration question

[Jonathan Troutt]

Does a PH probe need to be recalibrated after being out of your tank and dry for a few days? I am reading 6.5 ph in my tank

Yes. If the probe dried out it'll need to be recalibrated. They need to stay wet which is why they're stored and shipped with the little containers on the end
