My pool is surrounded by trees that will drop seeds until June. It's cold enough that we won't swim anyway til mid-June. I was thinking of filling up the pool and essentially doing the opening process without removing the winter cover. Obviously I'd have to pull it back a bit to reach everything, but I just don't want the nightmare I had last year with all the tree junk. I already took a peak at the water, and its crystal clear. Just wondered if there were any issues with leaving the winter cover on for a while.
