Jax racks 40 gal sump kit

Getting ready to assemble my sump trying to get a idea on spacing for the skimmer and refugium was going to use a submersible pump but thinking of getting a external pump

Jax Racks is awesome, used their kit on my frag tank build, check it out under my profile pic if you like. I'd go with an submersible return pump, saves you extra drilling and hassle.

Should i do drain-skimmer-refugium-return? If so should i make the refugium space bigger than the skimmer bay ?
