Been trying to keep a small (55ga) tank w/ a few fish and some coral. Been at it a few years, but much time on road made proper attention difficult. Retired now, recently back from an Australian vacation, snorkeled on Great Barrier Reef, and found out what it's really like. With rekindled enthusiasm, I have purchased a 29ga glass tank, got plexi baffles, skimmer,bio balls, hang on overflow box, return pump and misc plumbing parts. Have done some research on sump/refuge design, but am confused as to best configuration. I woul greatly appreciate any guidance as I stand, silicone at the ready.
