Split drain or split return?

[schroeder]

The design recommendation that i heard suggests having all of your drain run into the skimmer section, and have your skimmer pump output should be the same as the return flow to the tank.
(ie: if after plumbing losses, you return 300GPH then you skimmer pump should move at least 300GPH)

So I guess split return would be the easiest to do, but ideally I would have the water run from the skimmer section, into the refugium, then run to the return section.

This wouldn't work well for all sump designs, because of the high flow through the refugium...

I was intrigued by this concept and am trying something similar on my nano, but without the skimmer. I intend to employ a similar design on my next tank (40b) so I'm testing it out.

...viewable refugium? Maybe not a very pretty design for that eh?
