Most of our leaves have fallen and I could remove the cover at anytime. It is just a leaf net held down with water bags. Our pump has ran on low speed all winter, so I guess we didn't really close the pool, just covered. The swg doesn't generate chlorine until the water temp reaches about 55 degrees. But the water is still clear.

My main concern is the yellow tree pollen that we get in April. Last year there were several days the we had to clean the skimmer socks every day. Will the leaf net cover keep the pollen out? I don't think it will, but if it will, it might be a good idea to leave the pool covered till the pollen has settled. Any ideas?
