I have all my probes fully submerged in the sump, hanging on the side of the glass with the old aquatronica probe holders or magnetic clips holdin them. They (ph,temp,orp,) works fine. I also have 1 temp probe just lying in one of the external overflows just in case the return pump fails I can notice the temp difference between the 2 temp probes because all the heaters are in the sump. I do clean the probes in the sump every 2 weeks with a soft tooth brush.

Probe mounts also serve to prevent accidental dislodging of the probes. Case in point... a local reefkeeper used to just drop the probes into the sump. While doing routine maintenance, she accidentally snagged the cable for the temp probe, pulling the probe out of the water. She didn't notice. Room temp being cooler than the tank temp, the controller kicked on the heaters. Several hours later, her tank was cooked, everything was dead. Now she has probe holders which securely anchor the probes into position.
I use one similar to Russ. A square black piece of acrylic with holes drilled for zip ties to hold the probes to the acrylic. Two zip ties per probe, with room for three probes. Another set of zip ties attaches to the hanger, a long straight piece of acrylic which I have bent to fit the side of my sump. I don't have an awesome slide mechanism like Russ though, I just have a simple adjustment up and down in 1" increments. There are two holes drilled every 1" so I can move the probe holder panel up and down as needed and I just attach with zip ties. Pretty basic, but effective. I can take pics you want.

I use the styrofoam. To stop them from breaking apart, use a torch and give it a quick singe.

No... it was an entry-level controller without email capability and a audible alarm that could only be heard a short distance away.

Three things in life we know to be true. We will all die at some point. We will pay taxes up until that point and all suction cups will eventually fail. Great solution, adds etreme flexibility in probe placement, dirt cheap and if used and replaced on a fairly routine basis an excellant idea.

I would think a magnet would interfere with ORP. Oxidation-Reduction Potential is usually measured in millivolts (mV) which is a measurement of electrical voltage. I think a magnet might distort these readings by creating a polar electric field in the area around it.
I think this is what happened when I setup my ozonizer with an ORP controller. I was using a mag-clip as a probe holder. Another possibility for the chaotic fluctuations in ORP readings is that the probe was exposed totally out of the water for about 24 hours. I have read that some probes can be damaged this way because they should be stored in storage solution or RO water. Whatever was causing malfunctions in the readings, I'm staying away from magnetic probe holders.

Just got an email from Kelly at Aquarium Specialty. (S)he said they will probably start carrying the Aquatic Life probe holders now and might add them to their website just for me! That would be great because I will save on shipping now because their pc bulbs are at a very good price and I thought I would have to get the probe holders somewhere else. Now I can get the bulbs and holders at the same place!
What was this, link is dead.

This one from Eshopps fits the Apex temp, pH and ORP perfectly. Note that you have to feed the temperature probe in plug end first due to the cap on the temp probe. No interference from the magnets on my setup, and the magnets are very strong. Perfect solution in my opinion.

Or get one for less that doesn't require you to disconnect things
