I don't really know.. sorry... whats your return pump?
I see that you have a hob currently, are you thinking of setting up a sump/fuge?
I also have a mag 3 that worked well with my 30g if you are looking for a return.
If you are looking for a full setup I have a custom built acrylic sump/fuge and a cpr sr2 protein skimmer. I could ship the cpr but the sump/fuge would probably be pricey to ship. But pickup is possible.
edit: I don't know if you have any frags but I would be willing to trade as well... I saw that you have some candy cane and blastos in your profile.
