    I had stains when I opened this season too. Pretty frustrating, but pretty easy fix. Agree with Butterfly that your PH and TA need adjusting first, and sooner the better. That can be accomplished with soda ash (read and retread pool school). Don't add any more chlorine, as it needs be close to zero when you do the actual stain treatment. In the meantime, order some ascorbic acid online. By the time it arrives, the chlorine should be low enough to start.

    The link above on metals and stains has step by step instructions. Also, here's my thread on my attempt to remove metals:

    Good luck!
