The only time I have ever had algae in my pool has been while I was on vacation with the with my solar cover on the pool. It rained an inch and after the rain water sat on top of the cover for a week, green algae started to form. With a decent amount of water on top of the cover, there's no way to prevent water from spilling into the pool when pulling it off. My pool immediately turned a cloudy green color and it was pretty easy to clear up in 2 days with SLAM but just a big inconvenience right when returning from vacation.
Does anyone have any methods for preventing this while on vacation? When I am at home and using the solar cover in Spring and Fall, I will brush the water off after rain but this is not possible while on vacation. I have tried using a pump sprayer to spray SLAM-level water proactively on top of the cover but this doesn't seem practical for more than a few days or if we get a heavy rain.
