Interesting topic, although I would lean towards lack of skimmer efficiency being under considered. Even with a BK skimmer on not enough water, I don't feel I'm pulling enough.
But let's assume this is a sound theory. Would it not be easier to put skimmer on a timer? I suppose pump restart issues would need to be considered, I know lots of people warn me with the BK to never turn off the pump

If you dosed skimmate back, would you dilute it? Is there toxicity concerns over concentrated skimmate? Dunno.
