Hi All seems I have open my pool this year and once getting it balanced I seem to have a light brown stain that appeared all over the bottom of my pool a few weeks later. It's not on the side's or around my ladder or along the edges where the walls meet the bottom of the pool.
I shock my pool weekly and the shock where it lays seems to get rid of the stain and make it blue in those spots.
I'm not really sure if it's a metal problem or a algae problem but since I don't see it on my ladder as usual then I think it's a stain issue. I'm running a perma salt system and just checked my copper levels and it appears to be between 0.4-0.5. I have reduced the dial on my perma salt down from 2.5 to 2 in case it was producing to much copper. This is what my pool place recommended for me to do and it's been about four to five days and I really don't see a big difference like they said I should, it may have improved a little bit but not much.
They recommended me to add this metal conditioner remover and another bag of shock and that what I have done so far.
Would it hurt to add something like ascorbic acid to my pool?
Thanks for all your help
