Tank is 6 foot by 2 foot by 2 foot, (600 litres), with a skimmer and phosban reactor hung on the back. Tank is doing well after 2 weeks, and I have not lost any live stock. Phosphates are a little high at 0.03, but are coming down I think. Tank is setup in much the same way as my 100g, and the way I would recommend to any new reefer.
