I'm currently in the process of setting up a 75g saltwater tank with a 20g sump. I'll be running 2-3 power heads, proteins skimmer and a return pump that flows 950 gph. I was wondering what size return line I should use. At first I was thinking ¾" but now I'm not sure if I should go up to 1" or more. Any advice would be appreciated.
