which sump configuration?

[billford]

i have a 200g sump in the basement that i am adding a new skimmer and chaeto to.my skimmer needs to be only 8 in.deep .so should i build a platform on the bottom of my sump for my skimmer or put a rubbermaid tub on top of the sump that the return water flows through first before spilling into the sump though a hole thats cut to 8in.and put the skimmerand chaeto in there. the sump is empty its mostly for cooling and adding volume thanks for the input
