Just a small update...
I finally finished up my skimmer today (almost

).
The skimmer measures about 30" high (including collection cup)... there are no flanges on this thing, the collection cup is a push fit, and the riser neck is big enough for my small hands to fit through. The skimmer is fed directly from my overflow drain, and a WP4 (a Sedra 9000 knockoff) is used for recirculation with no venturi. I eventually plan on buying a Sedra 9000 needle wheel impeller in the future... but for now, I'm happy with the results. Picture was taken an hour after I had the skimmer running. I still need to make up a lid for the collection cup... for now a piece of scrap aluminum will have to do
