Hi experts,
I am new to the site, but have been reading for a couple of weeks now trying to find answers to my stain problem. I keep my PH and chlorine under acceptable levels at all times, yet around two or three weeks ago I noticed a couple of dark spots (dark-brown when you look closely) that have quickly spread all around the bottom of my in-ground pool. I tried Jack's Magic Stain Identification kid with no luck. None of the packages seemed to make a difference when applied to the stains, as directed. I have uploaded pictures that I hope help ID the stains. The stains appear to be black in the pictures, but if you zoom in you will see they are actually dark brown (dark red?)
Please help.
