Hi Im stumped, I have been cleaning a salt water pool for a year now no problems, ph 7.2 it is covered and the Cl is stable at arround 1.5.
in the last 2 weeks i have got brown stains appering on the bottom and brown turning to black on the side in a few places, it is spreading, the solidity of the salt is 5300 so the main readings are ok. i have tried removing the metal and black algie remover but no change. HELP. Chris
