those dimentions are for a 90 gal tank. as far as a sump i would look at as big as you can to fit in the stand. 6 bulb t5 fixture will be more than enough to get you up and running. just remember you need to replace those bulbs evry 8-12 months. start slow and be patient. i know it was stated earlier but i would look at building the overflow rather than drilling this tank, when the upgrade bug bites in 6 or 8 months then you can have one built to your specs with the overflow that you decide you like lol
