I assumed the brownish sticky ring around the side of my pool and foamy bubbles were from the algaecide I used a couple of days ago. I started thinking -------about a week or so ago I retrieved a float that flew out during a storm. It was sitting on a very small natural spring area in our yard. There was the same brown sticky tar-like stuff on the bottom of it. I tried to get it off, but figured it would just eventually go away when it was back in the pool. Do you think this is where this situation came from? Or that maybe the algaecide I used reacted with this in some way?
I changed the filter last night, added more chlorine and scrubbed the ring off the sides. Today--the foam is gone as well as the ring.
