Hi, I am brand new to aquariums. I had a small freshwater aquarium growing up but now I’m wanting to get a large saltwater aquarium for my kids. I’m don’t even know where to begin. Do I need one with a built in sump or is there a difference between the physical aquarium between salt vs fresh and how do I get everything set up? I’m not really concerned about cost, just don’t know where to get started really. Think I’ll probably buy a used aquarium off Craigslist but other than that I don’t know what to look for. I’m thinking 200 gallons or more, and I would greatly appreciate any advice. I am a complete novice so any help is appreciated, really want to do this to get my kids involved. Thanks!
