I just wanted to qualify for this forum!
Just kidding, I knew I wanted to go bigger once I got a house, and I saw Toms at the reef shoppe in Roch and thought it was the perfect size. Actually wanted to go w/220, but got the veto from the wife.
My buddy that got me into it has a 135 and in my opinion you get so much more depth (front to back) for aquascaping and appreciating out of a 180. I view it as the smallest big tank.
Using a tigershark for return, but it's dialed back to about 50%. Went with it after MUCH debate for it's head pressure rating. I could turn it up more but the overflow pipe just rushes and gushes and gets messy, so I upped my turnover in the display with 2 Tunzes and 2 Seio M820's.
Any help you need just pm me or post on URS, happy to help Mike.
