Every year I get pool fever around this time to open so I can get things balanced before the warm weather really hits. However, I have one tree that spins off tons of helicopter leaves in the coming weeks. Clogging the skimmers. Temperatures are rising fast and I am concerned (like I am every year) if I don't get chlorine flowing that algae could set in. So I am thinking, can I leave the pool cover on while I run the filter to keep the helicopters out of my skimmers without any adverse issues? I am thinking I will clean, shock and install my pump, filter SWG etc.. place the cover back on for a week or two until the helicopters pass then uncover it for the season. Of course I will check it daily for chem levels but at least keep the helicopters out of my skimmers while I am at work so they don't strain my pump. Thoughts?
