What stain removal process are you referring to? I tried Jacks magic last year and it did not work. If you have a stain removal process on this website can you please supply a link or point me in the right direction? I'm not looking for a simple solution, but with my FC at 0 and high temps the next week I had to either try it, or give up and rechlorinate.

Right now the AA has removed most of the stains. I do not want them to come back. It did lighten the heavy organic stains in the deep end, but I would be very happy if you have a process to follow for that, aside from draining and acid wash, which I have considered.
