I'm being told that if you close late and open early (Oct - Apr) you
dont need a vinyl cover. Mesh holds out just as much debris but the
vinyl keeps the sun from creating algae if the pool is closed early
and opened late. Mesh is lighter and easier to open/close and is less
prone to mildue since it is easier to dry out. Originally I wanted to
get vinyl with 2 mesh squares to allow drainage (LoopLoc). My
thinking was that it would keep out more debris and would be less
prone to staining the plaster. I would love any feedback.
