Solution

The only guaranteed solution to metal staining is to empty your pool and have it ‘Acid Washed’ by a pro. But there are DIY fixes you may wish to try before parting with your hard earned moolah. Here they are:

WHOLE Pool Stained:
  • Add Metal Remover
  • Add sufficient hydrochloric acid to lower pH to 6 or below. At a point pH will be low enough to bring metal deposits back into solution where the Metal Remover will keep it suspended as pH is readjusted to normal.
  • To readjust pH in FIBERGLASS pools, use Alkalinity Increaser. For MARBLITE pools use Soda Ash.
PATCHES of Staining on WALLS:
  • Add Metal Remover
  • With pump OFF and still water, pour either hydrochloric acid or dry acid granules down the wall directly over stained area and leave for a while, checking regularly for improvement. If successful, the metal deposits will dissolve back into solution where the Metal Remover will keep it suspended.
