i'd recommend not using an overflow box and just drilling your tank. even if you have it drilled at sea of marvels, i think hung only charges $20, which is less than an overflow box and way better.
you can get 10 gal tanks for 10 bucks pretty much everywhere, i think i just bought everyone's 10 gal tanks... sorry... i had to get some extras at the store.
i have a CPR Backpack skimmer i'd sell you if you wanted one, if you get the skimmer i'll drill your tank for free.
for a college budget you may just want to buy your RO water by the gallon for a while, most lfs's sell it for between 25-29 cents a gallon.
I'd recommend a deep six hydrometer instead of a refractometer, you really don't need to be that accurate, and the deep six is kind of a standard in the industry.
anyhow, i'm in cedar rapids if you want that skimmer or need help.
