Marie -

I have a question for you...

Now that we've removed all the iron from the pool using the makeshift filter, we were left with some liner/skimmer staining. I read the ascorbic/citric acid treatment sticky - but you suggest immediately following up with a sequestrant. Do you think I could run my sump pump/batting filter during the ascorbic acid treatment in order to trap and remove the metals rather than having to sequester them?
