Vinyl liner stain

[shircri]

Thank you so much. This afternoon I crushed some Vitamin C and let it drift down on the stain and just watched as the stain disappeared! It covered about a 4'x4' area of the vinyl of a 30,000 gallon pool. Do you think it is necessary for me to add the metal out now or do you think it will just filter out on its own?

Metals don't filter out That is why the sequestering agent is needed. It may be ok for a while, but as soon as you get your chlorine high, and your ph is over 7.6, you will see the stain start to form again. I would add the sequestering agent to be on the safe side.
