Due to how my pool steps are (elevated lip above concrete), when my auto cover is closed, it isn't flush against my concrete, which leaves a few inch gap (photos attached) causing mulch, pollen, etc. to occasionally blow into my pool. Does anyone have any creative suggestions for how I could lay something next to this opening to block it? I've considered pool noodles held in place with weights, but this wouldn't wear well through winter (I live in the Northeast). At a minimum I need a solution for the winter when the pool is closed, but wouldn't mind something easy enough to also use during summer/pool season. Thank you!
