My question is... Should I have my pump set on high to skimm a lot of water, or on low to maximize the contact the bubbles have with the water?

Maximizing the contact time is the best way to ensure your skimmer makes the most out of what it is designed to do.

The smaller the bubble and the longer it takes for that bubble to be exported will ensure that bubble is covered in the most amount of protien.
