We have seen statistically that (or maybe we havent) that 2x turnover through the sump is generally more than adequate and pretty close to what WWC uses in their methods. Why do I so commonly see new tank builds sizing their return pumps to be able to handle 25x-50x? Granted you loose some flow in the plumbing and maybe for a DC pump you don't want it maxed out 100% of the time. The old 10x sump turnover rule is archaic when return flow was used to make up a large portion of total turnover, before we had high end power heads capable of insane flow and adjustability. Turning over your tank so many times will just strip your reef of nutrients needed to grow.
Maybe you want to run additional equipment off a manifold? IMO thats just reducing the amount of redundancy in your reef and increasing the chances of equipment failure when your not around.
