pH Probe Question

[Beverly]

The ball tip of my pH probe has a growth of coralline algae on it which I want to get rid of. Currently have the probe in a glass of tapwater for the last day, but none of the coralline has died yet. Am thinking of soaking it in vinegar, but am afraid the acidic nature of the vinegar will destroy the usefulness of the probe.

Any ideas of what I should do? Keep soaking in tapwater then scrub with a toothbrush, or soak in vinegar?

I soak mine in vinegar for a few hours every few months.

Jonathan,

Do you recalibrate it after soaking in vinegar, or just plop it back into the tank?

[Delphinus]

I would recalibrate it, yes. Actually it's probably not a bad idea to recalibrate regardless, on a periodic basis.

Tony,

Regular calibration sounds about right. Will do.

The vinager trick works great. I also have had to use a very soft toothbrush in the past but I don't think it's reccomended.

After time the whole probe needs replacing anyways.

Calibration after cleaning gives you the best results.

HTH.
