  I have a fiberglass pool with brown stains on sides and walls. We
  have tried Ascorbic acid which does get rid of the stain immediately
  but then over a week or so the Stains are back. I keep up on all
  chemicals and keep them at a good range. I do have trees over pool
  but the polaris does a good job of picking them up. I also have a
  heater which is about 8 yrs old. I am pretty sure it is not algae
  since the chlorine level has been at 5ppm for the last 2 weeks, also
  i put algaecide in pretty regularly. Also the staining has gotten
  progressively worse the past couple of years and with Ascorbic acid
  being $30 a bottle that gets a little expensive to put in regularly.
  I think it could be the heat exchanger letting copper into pool
  water. But not sure. I hope to God this isnt permannent. please
  help if you can….
  
  Have you had your water tested for copper? If the heat exchanger was putting
  copper in the pool water the walls would be a turquoise color and not brown
  so I do not think it is copper. After you use the ascorbic acid you need to
  use a metal remover compound in the pool water. Leslies has something called
  Metal X that binds the metals in your water and keeps them in suspension thereby
  preventing them from staining your walls again.
