Hi, I am really thinking about upgrading from my plain 10 gallon tank, and I'm not looking for anything huge... I am really looking into the JBJ 29 gallon nano cube, I want something this size or so (still has to be able to fit in my dorm room lol) But as I read reviews the cheapest one seems to have a problem with the heat? and the middle option (intermediate LED) doesn't seem to have decent output? And then with the expensive one you get what you pay for... but I'm not sure I want to drop 500 bucks on a tank... any suggestions? or alternate tanks that look the same? also any reviews or opinions on the JBJ nano cubes? Thanks in advance =).
