It will work fine. Go with 3/8 poly tubing for the runs and ls/17 for peristaltic tubing.
I think EvMiBo as posted up above has a brushed unit fs.

Yet another series of questions:
is anyone running their pump higher than 80mL/min? I have already invested in L/S 16 tubing and the max output on my new pump is 80mL with that tubing... I don't have the graph in front of me but the next two sizes for me would be L/S 25 and 17 (allowing for higher outputs/min). Would it be worth it so the drive is doing less rpm's?
The L/S 16 tubing fits snugly on the barbs of my GEO612, so I just did that initially. I assume people are using something like reducing barbs to match up their larger peri tubing with the smaller tubing required for the reactor barbs? Sorry if these questions are basic - painting a picture is just essential for me.

Yes, It will be worth the jump in tubing size.
I prefer to change over all the fittings on my reactors to the john guest (RO) style push to fit connectors. If you are going to put in a usplastics order get them from there. They are half price of lowes/hd and you get name brand JG.
Run 1/4" or 3/8" rigid poly tubing to the peristaltic pump. Then you use the 6-8" of masterflex tubing.

Loosely anchor it, you don't want it to be too much a pita to replace it 10 years down the road 
. Once every couple of years depending on how the line looks put both ends of the tubing into a bucket of pure white vinegar and run it like that for a few hours. Should clean the tubing up like new. Might be easy enough to do it each time you break down the reactor for a thorough cleaning. I do it once every ~3 media refills or about once per year.

I ordered some L/S 17, reducing barbs (1/4" x 1/8") and vinyl tubing.
Maybe I'll learn with more reactor experience, but what makes the push to fit JG connectors + rigid tubing so desirable? I can imagine some convenience in quick disconnect, but how often do you need to actual do that? Furthermore, isn't that rigid tubing (used in RO/DI filters) a hassle? Fill me in! Maybe picture?

Peristaltic pumps pulse water, it is not a constant stream.
This pulsing can work the tube and over time will shorten its life. The rigid tubing is simply more durable.

Cool, that's kind of what I figured. Unfortunately my setup is pretty cramped and I fear the rigid tubing not flexing where I need it to.
Anyways, my 7523-70 arrived yesterday. Just waiting for the new L/S 17 and straight barbs to set it all up. It's in excellent condition, got what I think was a great deal ($250) especially considering it has an easy-load head.
Digital brushless!

Awesome! Looks like its in great shape as well.

It is! It looks like it has been barely used! Btw, I got it on ebay. There were several bidders - I was wondering if any of them may have been any of you! :lol2:

I know this is a little off-topic, but could you recommend a good dual head peristaltic pump that could serve as an automatic water change system? It would need to move at least a couple gallons an hour to run at 25% duty cycle. I'd also need about 20' of head pressure.
Any help would be appreciated!

I know stenner multiple head pumps have a pretty good rep. Personally, I've never used one but it seems like this one (below) might fit your needs (1.83gph and up to 25' head)... I'm sure others with a bit more knowledge will chime in.

Furthermore, I think (off the top of my head) masterflex makes multiple head heads that are in the C/L line of their pumps.

Most of the Masterflex units if you get a good deal on the drive can have more than one head stacked up.

When doing an AWC system you really need one or both of the pump heads to have adjustable occlusion. It helps balance the system.
If noise is a concern the brushless units are the way to go. If you look back through the first few pages of this thread it has model numbers you should be looking for.
If you want some direct help feel free to pm me. They can be daunting. I also recommend running a smaller tube like a ls16 for AWC systems. They handle greater head pressures therefore they are less susceptible to head loss when making crazy long runs.
