I have been researching SW for a short while. I am still in the research stage and realize I have been kind of "all over the place" in my research and I am getting back to the basics. I am trying to decide the best tank size for my first tank. I have decided the first tank will be a FOWLR tank. I will probably expand that tank to a REEF tank down the road as I get comfortable with maintaining a SW system. Here are some of the things I am considering as I think about the tank. 1.) I want to go big enough that I don't make it harder on myself as a beginner in SW. So water volume is an issue. I know, bigger is better. 2.) I am not very tall, at 5' 2" working in my 30 gallon hex tank is sometimes a chore. I stand on a stool but reaching the bottom to place delicate plants that I can't get seated well with my tongs... I feel like I need longer arms. It is 25" deep... I would not want to have to work in a tank any deeper than this and I really would rather not work in one this deep. So when I see the big huge tanks... they are so deep that I think working in them would be a pain. I wonder if it wouldn't be easier to keep 2 X 75 gallon tanks than to keep 1 X 150 gallon tank.(of course, these are future plans) Any opinion on this would be awesome to hear. 3.) I also already have a 55 gallon tank that could be converted to SW... but I think I would rather just shop around and find something a little wider from front to back... like a 75 gallon. 4.) My other thought was start with something not quite so big... like a 40 gallon breeder and add a 20 gallon refugium to it for volume. Do any of you think this would be big enough for a beginner starter tank? I really do think I could get a bigger tank on Craigslist. Problem with a lot of the ads I find on CL is that they either want to sell a very old tank that I am not sure is still watertight. OR... they want to sell a complete setup right down to the livestock... I want to do most of this myself. LOL I guess maybe I should be grateful that there are complete setups out there for great prices... but a huge part of the fun and satisfaction for me is the learning process and doing it myself even if it does cost me a little more in the long run. So what are your thoughts on tank size? What is the ideal size for a beginner?
