White Slime on Ph Probe

[Biglurr54]

I have an odd thing occurring on my PH probe in my calcium reactor. I started with a pinpoint probe in my reactor. It started having a while slime bubble that grew from the base of the electrode. The pinpoint ph probe in the sump did not have this slime. I thought it may have been leaking gel from inside the probe. When I upgraded reactors, i put in a new double junction probe. This probe has the same white slime bubble growing at the tip. Has anyone else experienced this? It is only occurring in the reactor.
