I have a new 125 gallon that I will eventually be setting up as a reef but for now will start working on getting it set up as a fish only with live rock due to the fact that I can't afford the lighting yet. I have a 55 gallon that I will be using as the sump. Is this big enough? Also, I want to get the aquarium drilled in the back to put overflow fittings in. How many holes should I have drilled? What size should they be? How many GPH should I be pushing?
