Mine is the Reef octo110 but wasnt near that much $ it is rated up to 110 gallons hence the name. I dont have frags yet.... but I spent around $450 on tank and stand(no canopy yet), $100 on 2 koralia 4s, got old sand from a guy in San Antonio(just cleaned it up real good as it had some dieoff going on), Made my own sump for $20 approx. 20 gallon, and a $65 on the return pump. Also got my light from this site for $100. The rock is what gets you I paid $3.50 a pound for live rock but used 20 pounds base rock. There are alot of small stuff like heater, test kit, thermoter, etc.
