A guy gave me this tank today, and I am confused as to how to set it up for the sump. It has 5 holes drilled in the bottom. three across the front about a foot fron the front of the tank and two towards the back. bot nut close enough to the back to put overflows in. the set of three is piped together and the back two are piped together. I know pics would probably help but I have no way to take them right now. Any help is appreciated. Thanks
