I drained my pool to a little below the skimmer line for winter. I went out to add some water filled milk jugs to the winter cover to hold it down in all of the wind we get and noticed the water line was right at the skimmer level. I don't have a skimmer cover so it's essentially open to the elements and have the return plugged with a screw in plug. Should I drain the water a little lower below the skimmer or is it okay with ice right at the skimmer level?
