Confused help with refugium please 29g

hey guys and gals I have a 90g with dual overflow drains. I also have plumbing and a t to put both drains into a filter sock. I am using a mag 12 and a rio2500 for returns. I will be running them up the exterior back of the tank. If some body could help tell me how they would do the baffles.  I also curious how many high the baffles should be to leave room for water in case of power failure. should I put the refugium part on one end with one of the two drains to fill and the other drain to my filter sock. that way I could have my refugium deeper, and the water from refug overflowing into the sock part and lastly a compartment for my pumps,  skimmer ,etc.....the refug will be a 29g standard tank ( biggest question is how many gallons to leave empty)
thanks everybody for the help  Frank

Im useing a 29 on my 65. If you want to come and look your more than welcome. I can tell you why it was built the way it is and show you what I would do different next time around.

Shane is right on with the overflow answer.  When I set mine up I had no idea what the water level would be until I tested it.  I knew that it would drain down to just below my durso but did not factor in my sea swirl siphoning down below the outlet.  My system handled it just fine but every single setup is different.  I would also do a closed loop on a different power outlet than the return pump.
