    Oxidizer after AA treatment

    I know if you bring the chlorine level up too quickly after and AA treatment for metal stains, the stains can come back. Will the same thing happen with an oxidizer (so called non-chlorine shock).

    No, because the non-chlorine shock won't be raising the pH and probably won't oxidize the metal sequestrant though I'm not sure on that (depends on the specific metal sequestrant).

    The main issues with chlorine are that increasing the FC level increases the pH and chlorine oxidizes the metal sequestrant releasing the metal back into the water.
