Thanks, guys.
I guess I never really considered that the volume of larvae, eggs, ect from a DSB was that significant.
I don't know how to effectively "size" a DSB, but I do have it in my mind that given a large enough surface area, and the proper depth, of course, that a DSB should be able to handle all naturally occurring detritus material. (which excludes any extra chemicals that would come from our artificial salt, additive over dosing and processed food)
My new set up here has a 180g sump/refugium that has a 4 or 5 inch DSB. I've really noticed a difference with detritus accumulation, or the lack of, compared to the bare tank sump set up I had before. The sandbed in the sump/refugium has NO detritus building up on the pumps, floor ect. I can't help think that if I had a big enough DSB, I could get rid of my skimmer.
