I was thinking about return flow to my tank. I just won a mag 9.5 on ebay and with the sump next to my tank it will only have a lift of 1-2 feet. I was planning on using a SCWD for the return but why cut the flow to just 2 outputs. What are you thoughts on having adjustable ports in each of the corners of the tank? Since the tank isn't setup yet I could hide any plumbing in the DSB. I was thinking of using 1/2" PVC in the DSB to supply to the front corners and 3/4 for along the back and for supply from my pump. I figured this idea would help cut down on dead spots. Any comments would be greatly appreciated.
