Sump / Refugium Combos

[Okguy]

My design does allow the refugium to overflow into the sump (no pump required). I have a feeling that some of the pods do survive the trip up as my mandarin hangs out right by the return pump outlet most of the day (I use a Poseidon as well). I have seen some designs that incorporates a 5-10 gallon fuge above the main tank so that the pods don't have to go through a pump on the way to the display tank. My understanding is the above the tank fuge just needs to be slightly higher than the DT for it to work.
