Yes, put the probe in the 1st chamber.    The only benefit of the second chamber is to raise the ph.  If your going to measure the effluent PH in a cup in the sump, then the second chamber really has no value.   Unless for some reason you have a very small reactor, and your trying to add media volume.

Hmm lol I guess its not that hard to drill a hole in the first chamber and installing a "probe bulkhead" later on.

I bought plastic electrical  cord grips for the diameter of the probe.  They have 1/2" NPT threads on them.   I still have 3 of these left, and the tap.  Drilling and tapping acrylic can be adventuresome, just take your time.

LOL i just did them on the reactor bodies the other day.  the barbs ar 1/4-18 threads, but i only had a 1/4-20  I drilled and tapped 2 holes.  1 fit perfect and the other seemed about 1 sizes too small lol.  same bit and tap and used a drill press to drill... must be quality control on lowes' crap.
