DIY Rex Reactor/Heater/PH Probe/Temp Probe

I'm looking for a critique of my dry fitted DIY Rex Reactor/Heater/PH Probe/Temp Probe. The unit is about 24 inches tall and will be powered by an Ehiem 2213 at about 116gph (minus headloss) for a 5.5 gallon Mini M. It's a little taller because of the lower gph. The PH probe will control the CO2 via an AquaController (leftover from my reefing days) and is before the reactor for more accurate results. The temp probe will also control the heater via the AquaController. The pipe is 2 inches in diameter and the fittings are all Heyco Cordgrips.

Thoughts? Suggestions? Ideas?

1 Water In
2 CO2 Build-Up Release Valve
3 CO2 In
4 PH Probe
5 Water Out
6 75 Watt Ebo Jaber Heater
7 Temp Probe

That looks awesome!

I have been thinking about doing something very similar myself for my 20 Gallon...

How do you plan on sealing the probes in the tubes?

Heyco cordgrips are water tight.

Looks awesome. Temp probe might be a tad close to the heater. Only critique.

What are you flowing this with?

O yea, it never hurts to put a drain valve on these things! It helps to prime it and also to drain it out for maintenance.

Ahh. I see you didn't have it glued yet! Excellent.

I am concerned with the 2213 having enough "umph" to get that flowing nice. I remember I had mine with a small reactor and it was -ok-. Nothing spectacular, but it did the job.

Also, now that I am looking at the temp probe wye fitting, I would turn it around the other way so you don't get an obstructed pocket.
