Yeah thats pretty much what I thought. I think it will be fine...Well it better be. I am also wondering though if the overflow will be big enough to handle the 2" drain. I may have made it too small.

Just realized I have another small issue. My RO unit came with a faucet adapter but I cannot use it in my apartment because it is for threaded faucets (like laundry sink ones) and I just have the kitchen and bathroom sink faucets to use (not threaded just regular faucets). Is there anything I can pick up from somewhere like home depot to use?

Actually the glass is too tall. It just barely leaves 3/8", maybe even a bit less. What a pain...I guess I have to have new glass cut. I don't think they can trim off just a tiny bit for me.

This is all because the eurobracing is a bit lower and thicker than I thought it was. Its 1/2" glass.

A few more things Im really not sure about. I started doing my plumbing and realized that there is not much room to plumb another herbie drain between the refugium and sump. Im also wondering about the fact that the refugium is not raised up much higher than the sump. Is this even going to work? If the refugium is draining from near the bottom and then into the sump by gravity, it would barely be a drop at all. I don't know if that makes sense but this doesn't seem to work out in my head. Is it possible just to keep them at the same level and connected through bulkheads near the bottom. That way just allowing water to flow through the refugium into the return section of the sump?

I will draw a picture

If I understand you correctly I think it will work. The only thing is that without the "drop" that you will not be able to push too much water through the refugium because the back pressure might cause the refugium to overflow. So you might need to experiment with flowrates to find the optimal rate, but I think it's not a showstopper. Good luck!

Super rough and simple but here we go. Just something basic like this. And yes, I was actually concerned about back pressure but I do not want too much flow through the refugium anyways. I have seen this done before but I do not know how it worked exactly. It does seem like it would be hard to get flow moving properly through the refugium.

Like I said before though, because of space the second herbie would be hard to do. plus I do not see how it will work without much of the height difference. I may be missing something though!

Oh - hmmm - why not just raise the refugium a little (put it on bricks or build a little platform) so that the top is at the same level as the top of the sump? Then it can't overflow (well, not without the sump overflowing too).

Actually it is already a little above, so I guess I could just leave it as it is. Im really just running into problems with space. If I had more space in height and width, this would all be no issue.
