Hi everyone and thanks for all the great advice,
I recently had a pink algae problem and had a hard time getting rid of it, I shocked the pool and it disappeared but came right back so i went to the pool store and bought some "Pink Treat" from united chemistry and followed it up with 2 lbs of Trichlor. This took care of the pink algae but now I have a yellow stain in my spa that won't brush off. Does anyone have any idea how this came about and what treatment I should use to get rid of it? Any help would be appreciated.
