Digital Aquatics Ph Probe Reading -0.22

[Fishninja]

I bought the digital aquatics reef keeper lite used about two or three months ago and the ph probe has been working fine. I never calibrated it but it was shipped wet so i wasn’t too worried, but about a week ago the probe started reading -0.22 ph??? Does the probe need to be replaced or does it just need to be calibrated?

Probably is due for replacement. You can try recalibrating, but that didn't' work for me when mine went.

Probes should last longer. Try calibration. Also make sure it is not dirty.

Thanks for the replies. What is the best way to clean it?

I soak mine in white vinegar. Then use an old toothbrush to clean off the remaining residue.

Just be careful not to break the glass bulb in the tip.

Yes use a light touch and soft bristle brush. If you get residue around the base it's hard to soak it off sometimes.
