Ok....so i'm starting a build thread for my new 60 gallon cube. It's gonna take about 3 of 4 months to build, but i'll have pics every step of the way. I'm gonna need some help building it, so any input is awesome! Here's the tank.... Now what i need are ideas. How big of a sump should i use. 10 gallon tank? 20 gallon? What size?
