Looking for reccomendations on how to layout the water flow to and from my sump for a 90 gal tank. I've always had a hang on over flow and used power heads to move water. In my new tank I want to eliminate these items and am looking for info on size, location and number of holes to drill into the tank to provide optimal water flow. Also if a closed loop system is recommened to provide more flow what size pump should I use and where and what size holes should I add for it?
