I am in the process of getting some stuff together for either a 12g or 15g nano reef. I love my 120g but it is in my basement and i really want a little bit of the ocean in my room and a nano is the only option since my room is pretty small. I know just about everything that i am goin to get equipment wise except for a skimmer. I have seen a bunch of "nano" skimmers online, but i have no clue which one to buy. Any ideas or suggestions on a good one for that size tank. My only parameters for now are that it be affordable(under75$) and hang on since i won't be running a sump.
