Help needed! I blew 2 gallons on non toxic antifreeze into my pool when I opened it this weekend. It settled on top of the pool creating an oil slick. I have put in 8 bags of shock to kill the algea but it can't break the surface. The shock combined with the antifreeze has created a white oil slick on the surface which foams up in my skimmer basket. How can I get the antifreeze out of my pool without draining all the water?
