This is a classic Euro-Reef skimmer body. $20 shipped, $10 local pick up. I'll also entertain trading it for a frag of something I don't have. Here are the specs from MarineDepot.
I ran this skimmer on a heavily stocked 50 gallon mixed reef (see retired 50 gallon link in my signature) for 8 years and it worked great. I upgraded to a larger tank, got a bigger Euro-Reef skimmer, and therefore don't need this any more. It originally ran with a Sedra 3500 pump, but the pump failed and has been discarded. More recently I ran it with a Tunze hydrofoamer (way overkill). There's no pump included with this sale.
I also have the foam sleeve that goes on the outlet pipe and the air supply hose that are included. If you'd like I can also throw in a 5" wide bottle brush. It works well for cleaning algae and coralline from the inside of the body.
I should be around this weekend, but let me check with the boss... I mean wife. I'll PM you so we can make arrangements.
