I also installed the spigot you can see up on the wall as well as a drain pipe so I can install my rodi unit on the wall. now i just need to plumb some pipes into the barrel and install a pump, but im still waiting on uniseals to come in the mail
Time for an Update:
Had a tank crash back in june/july time frame. Lost quite a few corals. Tank is rebounding but has had a bit of a cyano problem since the crash.
Some close up pics of the happy coral:
