I have a dedicated refugium. It is a 20g tall. I have drilled one end and put a bulkhead in. Water flows out of my tank via my overflows and one drain line dumps into the fuge. The water then flows out of the fuge into my sumps. This is not an uncommon setup at all. Many larger sump systems have the fuge setup to allow slower water rates. With smaller sumps it's hard to do that because you just don't have the space or the extra plumbing. Also with smaller setups there isn't as much need for it. Take your tank for example. (46g bow??) you havea mag7 as your return you aren't getting 700gph at the return in the tank so that means you aren't getting too much flow through your sump/fuge. On larger tanks you can split your drain lines and have them feed different areas of your sump. Make sense?
