Thanks! I had checked the pH regularly and don't believe it was high when the liquid chlorine was added. I have no idea where this product came from, or its quality, and will have to go look at the label and see if I can get more info on what exactly it was. When I glanced at it, I noticed that it was 12.5%, and that is all I noticed.

I'm probably being obtuse, but I haven't found the thread you mentioned about removal, but would be happy to follow it exactly once I locate it. I will also happily return the Metal Free, and Im assuming your thread recommends a more appropriate product.

I have not run the chlorine down to zero as I definitely agree that I dont want to deal with algae too! Thanks for your reply!
