Pinpoint Ph Probe Leaking!

[shawnlx86]

I received a pinpoint PH probe to go with my reefkeeper 2 a few months ago. I did not get around to setting it up until this week and when I opened the pox there was a stain @ the end of the probe. When I touched the end of the probe it was wet(oily). If I wiggle the rubber piece around I can get the substance to leak a little where the rubber piece meets the plastic. Is this normal, will it be fine when it goes in the water, should I tie a ziptie around the end of the probe, do I need a new one?
Thanks, Shawn

The non cord end comes with a plastic cover that is wet. The bulb end is not supposed to ever dry out. Remove this cover before using it or calibrating it, as the instructions indicate. Keep the cover and wet it with RO if you store the probe out of water for any length of time. If you are talking about the cord end, I'm not sure...

Don't I feel stupid now, so just pull the clear rubber feeling end off and put probe in the sump tank?

Here is a picture of it without the cover. I had to read the instructions twice when I first got it, I didn't want to ruin it -LOL. Calibrate it first, then put it in the sump. The two suction cups are shot, like they all get regarless of the type. I have two of them close together and place the the middle over the PhosBan hose. Keeps it on place without actually suction grip or lack of.

If you boil the sucking cups for a little while they loosen up and with stick like new again. (boil time depending on how bad they are +/- time)
First let them sit in some white vinager for a while to clean them up then boil them.

Thanks, I will give it a shot on the Maxijets..

Just for reference if you were to break the probe's glass nothing but a solution of dilute hydrocloric acid would come out which would be absorb by your buffers. Just happened to see this in my Chem book so I thought I would share it. Oh the joys of electrochemistry.
