sounds like deja-vu for me. Look I've been down this road before and I think that everyone in this club started just like you but this is my recomendation.
1. IF you are stretched for cash and you want to do a reef tank
a. try to sell your eclipse hood
b. try to buy a larger tank (many people are selling tanks now get one that is 55 or higher)
c. get some good lights (pc, vho, halides) it going to cost you the same as a retrofit + selling you eclipse hood.
d. use your small tank as a refugium
e. don't worry about having to buy more live rock you can use other rock and mix it in with your good liverock, it will turn into live rock within a month with good lights.
I'll finish this later got to go to class also.
