I used this sump and refugium tank on my saltwater reef tank. Sump is 29 gallons and the fuge is 20. See pictures for dimensions.
The fuge is meant to be mounted above the sump and is drilled so that you can install a drain or a return though the hole. I used it with a drain plumbed through the hole and for the return I just ran it over the side of the refugium. $75 or best offer.
