Which tank would be better for a reef set up a 180 or 210? I can get a good deal on a new 210 (72x24x29) or pay a couple hundred more a get the 180 (72x24x24). I'll be drilling either tank out for the Synergy overflow so it just comes down to what size is best. I'm leaning more towards the 180 mainly because I figure it will be easier to clean.
