I purchased a home and pool that featured a ionizer.
This ionizer stained the pool and now I need to remove the stains if possible.
This is my second year with the pool and was quite ashamed with it last year.
I did the stain test year to confirm its was a copper stain.
I have not opened the pool yet, and planning to do so in the next few days.
I figure while the chlorine is low I can take some action, the questions is what action should I take?
So Please anyone with any advice please comment,
I believe waterbear is the resident expert??, but any help is apprecaited.
