I moved my tank over to a 40 gallon ADA tank, so if anybody wants a drilled 30 gallon Oceanic (tank only), they are free to pick it up from me. I am in Pflugerville.
I will put a picture up later, but until then a description will have to suffice. There are 5 holes drilled in the back. Two on the each of the back (on near top, one near the bottom), and one in the middle near the bottom. They are all for 1" bulkheads.
I had it set up with the middle hole as a closed loop drain, the two bottom holes were returns for the closed loop, the two top ones were drains to the sump, and the returns from the sump came over the back.
Send me an email (markaburton at gmail dot com) or respond on here.
Thanks,
Mark
