After a lengthy thread in the Equipment forum, back to posting here.
The budget has taken a beating, but we're still pretty much on-track. Just ordered the diamond hole-saws, bulkheads, loc-line for the returns, and black Flourite gravel.
Also, I picked up a 50G the other day off Kijiji, so now we're doing that as the display, and the 30G is the sump. More info tomorrow.
