I would definitely put a LOT of thought into the tank you want. Will this tank accomodate any setup your heart may desire? Is it too big or too smal from what you REALLY want? Can you afford all the equipment required for that size tank? Do you know what kind of equipment you will use? If you buy this size now, will you wish you had gotten something bigger within a year or two? Will this tank fit in your home? The reason I say this is that I turned my 46g bowfront from fresh to SW with no intention of doing reef. Had HOB equipment, LR and Live sand with flourescent lighting used on FW setup. This was Oct. '05. Then I decided I would do soft corals, bought CF lights in Dec.'05. Tank still empty. Then I decided my tank was too small for the fish I wanted and in May '06 bought new 90g AGA W/ overflow, UV sterilizer, 2 Aquaclear powerheads, sump tank, new pump, 50lbs LR, 40Lbs live sand. Tank still empty. Then I decided that I wish I had bought the 120 starfire glass I wanted in the first place because now I want to have SPS dominant reef and fish that are too big for 90g. Bought new LED light, skimmer, auto top-off, built sump/fuge, and I still ned to upgrade/improve my powerhead situation.I added a few crabs & snails.As of today that's all I have in my tank and will be ordering fish monday. Moral of the story, do TONS of research and study up on everything(fish,coral,EQUIPMENT!) before purchasing!!! Know exactly what you want first, I wish I had 'cause it would have saved a lot of time, $, and disappointment.
Good Luck!
