I have drained my pool roughly 24 inches to get a few inches under the skimmer hole. From what I see you want your cover to sag almost straight up and down and rest on the water to avoid excessive weight on the frame. My pool is 18' so I am thinking of going with a 21' cover (actual size is 24') that gives me 4 ft for the sag and leaves a foot of extra cover so secure around the sides. Has anyone else dealt with this...should i go even bigger with a 24' (actual size 27')?
Thanks!
Thanks!
