it looks very nice.
not to discourage you, but you should think about keeping it. i will guarantee, after you upgrade, you will wish you never gave this thing up. you will want two tanks (i promise). instead, you should leave that one up and running and just save up the amount you will sell this one for and put it towards the bigger one and keep em both going.
i know it sounds crazy but i did the very same thing you are doing only with a 60g reef. not a day goes by when i don't miss that thing.
think about it...
