Please help!!! This season has been horrible with the tree pollen. My pool got pollen at the bottom of the pool, I put the vacuum on and it picked up the pollen but now I have these mustard looking stains/spots all around the edge of the bottom of the pool and on some spots in the middle. Is there anything that I can use to remove the stains? I've used a brush to clean it and nothing happens. I'm thinking chemicals is my last resort.
Thank you in advanced...
