Non-metal stains

[mcase]

My pool was Ike'd and the stains from debris have lightened by about 50% in a year's time. Is there anything I can do to speed this up?

Elevate your level of chlorine...probably 25-50% over the recommended in CYA/FC chart.

You must keep the FC elevated until the stains are gone....you can't elevate it once and expect any result.
