xtyx.. what state are you in? I can answer some ?s for you, but as others have said, if this is your first experience with saltwater, it may not be a great idea. My first tank after getting back to it after 15 yrs is now a 125 g, but I had a crew set it up. You can email me at
ess-rt@earthlink.net and I will answer questions you may have. The first place I would start, if you REALLY want the already established tank, is the yellow pages and look under aquariums also look under saltwater fish, etc. You should be able to find someone in your area that offers tank maintance service for around 80-100$ a pop. Ususally once a month and the rest is up to you. This is a very smart move for you. Come to this site, ask lots of questions, read lots of posts etc. It isnt as hard as you would think, but you do need some experienced friends.
