Hello, new here and so glad I found this site. New pool above ground 21 ft round. We shocked it, drained it below skimmer and the opening where the water comes back in pool. took off hoses, put pump in basement. took cap off sand filter let it drain. Have chlorine frog drained that. got cover and put it on per instructions. No pillow. the company who installed told me we didn't need a pillow for this pool. left out plug in skimmer and plug for the other inflow. Did we do it right. should we plug the skimmer, place the cap back on the sand filter. we have water on the cover ... how much should we keep on it.
We live in Maryland and we have cold weather and snow ... Just for your thought... thank you for your help
