Hello & Welcome
Blue. I have an All-In-One 12g Nano Cube DX. I love it but it does need to be MUCH larger.
If I were starting out right now, knowing what I know I would go much larger. If I had the space it would be in the 55+ range. If space and design limited that much tank I would look in the 25+ range for all in ones. If I were buying one in the 20-35 range it would be the Red Sea Max. I've been watching it fairly closely as of later and sort of wish I would have gotten one. I have spent so much money in getting things for my current tank that's included in the RSM system.
Whatever you do, take it slow. Read read read and ask ask ask! It's WELL worth the wait!!
Good luck and again welcome.
Allen
