I was reading on the website that the MR2 is good for up to 300 gallons. I'm wondering if that is realistic and if that takes into account the 2nd injector (which it doesn't look like you have)? Or were you running this on something that size? I also read you can extend the tube, which I assume you would need to do if you added a second injector. I've no experience with MRC's, so I'm not up on them.
I want to eventually upgrade the skimmer on the 270 I just set-up and it seems like this might be a good way to do it, but I haven't had a chance to do my research on skimmers for this size range. I've heard nothing but good things about MRC's though.
I guess what I'm saying is, I'm interested, but need to figure out the details.
Also, you don't need a smaller skimmer (Euro-Reef ES80) or other equipment for something in a smaller size range (say around 90-110 gallons)? I know your selling your big guy, so I imagine not, but I figured it can't hurt to ask.
