Hello there. I have a light brown stains that is surrounding my pool and present on the floor in the shallow end. I have tried brushing but it just won't come off. I have added some pictures in. Also I am still waiting for my K-2006 test kit to arrive. Should be here on Thursday or Friday. Pool store said I just needed to add Calcium. I was at 190.
Thanks!
