This looks awesome, getting lots of ideas here....
In reguards to not getting surface skimming with the flow turned up, how is the "skimmer" piece attached to the bulkhead? If it is not glued, I would try replacing it with a pipe with a larger slot to see if that gets your surface skimming with the higher flow.
I would use a new pipe if possible so that you could switch back easy enough. another thought on the same lines would be to use a slightly longer pipe in that place (not sure if it is possible with the tank shape). Also if you cannot easily remove you could take a dremel to the slot to make it bigger.
p.s. I could be compeletely off base but thought I would toss this out as an idea.
