55 Gal FOWLR - seeking criticism

[turbo]

it's designed so 50% of the overflow runs to the refuge directly, (after baffling)
the other 50% runs to the skimmer chamber

the refuge overflows to the skimmer chamber

so basically the skimmer chamber is experiencing 100% of the flow. It's the last in line before the return pump. All of the water passes by the skimmer but only half of it passes thru the refuge.

Initially I thought I would dial down the flow to the refugium and have most of it go to the skimmer chamber, but then I realized that with the size of the pump I plan on having, I can't afford to restrict any of the flow in either pipe. So it's a 50/50 split.
