Massive sub pumps or cut into return line for skimmer?

Seems like you've more or less figured out what you need to do already. You know you've got some oversized equipment, so the logical solution is to get some gear that more closely matches what your system requires. Oversizing is great in some situations, but certainly seems to be causing you more headaches. I assume you chose such a monster skimmer for future requirements of a heavy bioload? That's a great idea, but since your set up is in it's infancy & you currently have a very low bioload, you can't expect it to be pulling that much out, regardless of it's size.

My vote would be to get some smaller pumps, or as you suggest, a much larger sump. Appropiately sized, smaller pumps will have the advantage of saving you some power $$$s.
