Sheets / Smears of Brown Deposit on Walls

<< Back to Troubleshooting

Possible Causes:

SA Water (even urban municipal) is highly mineralised and may contain elevated levels of various metal.

  • ‘pH Bounce’ (Low to High) can cause suspended metals to come out of solution and deposit on pool surfaces.
  • Pools filled by BORE HOLES are at elevated risk of metal precipitation (Even without ‘pH bounce’ as a trigger)
OK, Now What?
