Weird PH probe issue

[meadowsad]

I searched the forum and couldn't really find anything regarding this problem. My PH probe appears to be working fine for the most part, however I am getting dips down to 6.32. The dips appear to be 6.32 every time but they occur at random times in the day. The PH probe is relatively close to a Tunze pump in ReefCrest mode, would this cause the drops in PH when it changes speed?

Also this probe is fairly new and has only been installed for a couple days. I calibrated it using PH7 and PH10 solution, letting it sit in each solution until the numbers didn't fluctuate for at least 10 minutes.

Edit: The ReeAngel Client v3.0 shows these dips however the portal doesn't appear to show them.

Put the probe in a cup of tank water and watch for a day or two.

Will do! Thanks for the fast response. I assume this is to try and eliminate stray voltage as being a cause?

Correct

What's the next thing to check? I have the same issue (frequent temp drops on the ph reading) and it kept happening in the cup of tank water. Fairly new probe, a few months old. Thanks.

Are you also seeing it only in the Client?

[JoshSD]

That's the only way so far I know about it... The alerts from the client app.

I have not seen the low values when I view in the iPhone app.

Rebooted client machine and haven't been getting the alerts since, so it must have been the client as you hinted...
