Just read through first 5 pages. Was curious about pumping the RV antifreeze into the pool in spring as the cause to my spring start up problems the last few years. Blow all the lines out and then add the antifreeze. About 96oz fills the skimmer to the filter then put the gizmo in. The 2 return lines I add 4 gallons into the return which splits into 2 lines. When I open in spring I just let it flow into the pool. Last 2 spring start ups were not good. This year was horrible. 0 CYA and chlorine. MY cover is solid. I keep leaves off of the cover and pump the cover when there is about 2 inches of water on it.
