How is this setup: A 29 gal. tank, 30 lbs live rock, a divider in the middle, with 1 o. mercatoris on each side, 40 lbs live sand, 60 gal. skimmer, and 2 30 gal. filters. no daytime lighting, just a red fluorescent bulb for nighttime viewing. Is it suitable? I'm planning on multiple pvc pipes, and a few table tennis balls along with the shells and rocks for toys.
