I have a film of some sort that is apparent only in the skimmer basket. It seems to suspend whatever is floating on top of the pool at the time...small bugs and whatever is blooming or blowing in the breeze just now. Is there something I can add to the water to break down this film? No one has been in the pool for about a month or so, because the water is at 65 degrees, and I do not intend to close.
