Love the hair net idea, I just bought myself some! So I have the skim around. I just put it in last night. It definitely seems to pull in like crazy from what I have seen so far, no changes to pressure on filter. Only thing is, water seems to be coming in so fast that because my return is right below the skimmer, it is creating an aeration type effect across about 4 feet of the top of my pool water. So... not sure how this may or may not affect PH and TA if I keep it in there.
