I have a 30gal acrylic sump but it is drilled for 2 external pumps. I will trade for some nice corals. There should be a pic of it (while it was running) in my gallery.
I have a 30G sump drilled for external pump or you can seal with the right bulkhead, also I have brand new 1" bulkhead (separately) for it. Professionally made w/ baffles and leveled for internal skimmer, water flow is at an incline so there is not build up of residue and has glass brace as well....can't take corals at the moment...asking $50.
