I was watching the water in my pool go round and round the other day, and noticed a bit of turbulence where the upper return was swirling the surface a bit, and it made me wonder if I had my returns set right for optimum skimming. Up until that day, both returns were pointed towards the direction of the skimmer. After watching a wasp get pushed away from the skimmer by the circulation, I changed both returns to point away from the skimmer. Just wondering how everyone else has their returns set.
