But maybe both answers are wrong. Im not entirely sure how your sumps are set up!

Bingo! That valve controls the water level in both sumps, but evap replacement only happens based on the main sump water level. It was totally unplanned, but kind of neat when I figured it out.

You'll have exactly that same relationship between your fuge and the sump.

Yeah and if my fish do not behave I can threaten them with salinity changes!

So I picked up the glass for my overflow today and I may have made a mistake. This is to be a toothless overflow. I wanted it to be as close to the top of the tank as possible but I may have got it cut a bit too close. I got it cut so that it will only be 3/8" under the eurobracing. Will this be too close to the top of the tank? It should only be a very thin layer going over the overflow anyways but it looks close. What do you guys think? Does it make sense how I explained it?

I measured on mine and the water surface to the bottom of the Eurobrace and I have 3/4". I held up an edge at about 3/8" and can't see the distance being a problem other then when the 4 way goes around I might get rippling that high. It would just mean it would get salt creep on the bracing more than I get now. Maybe also the water level might go over if I plunged my arm in until the overflow caught back up.

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
