Are you thinking about a DIY probe holder? Why bother, here is what I did . http://www.usplastic.com/ There are many to choose from I used # 60429 hope this helps.

Or you can just use a 1/2" john guest fitting, with the inside drilled out!!!

i have thought about that also topfeeder but i don't have to much room in my sump to hold another box, but it may have to do. lol

would that 1/2" fitting be water tight though?

There is no other box to add, just tap your reactor!

I use a cord grip and it is water tight.
