I've been looking all over for information on this, but how is everyone running their sump return? I mean, what size and type of bulkhead are you using, and what plumbing are you using in the tank to direct flow and the such? I'm using 1 1/4 inch pipe from the DT to the sump in a Bean Animal setup, but from the return pump to the DC I don't have much to go on. I was hoping to use 1 inch or 3/4 inch on the return. This will be used on a 90 gallon tank, and I was shooting for about 800-950 gph in turnover.
