Figuring out what you need and how it works and effects your system is half the battle. I'm not saying don't get a complete system, but do a little research to see how they operate. There is a world of info and allot of great people on here, just ask and we'll help. Also our tanks are something we never Getty tired of showing off, look at a few systems to see what you want to accomplish. I started with a 55 all in one and it was too small for what I had in mind so I upgraded to a 75, now I wish I had gone bigger yet. There was a 75 w sump for a good price a while back . You can also find good deals on craigslist
