Lets go back to the beginning. In your
first post you said "stains disappeared". And then "added as told again, green disappears". Then right away things got confusing, with impossible test results, figuring out the pool volume, foaming, and adding way too much chlorine.
Can you tell us more about those stains? What did they look like and do you remember what the treatment was that made them disappear?
If those stains were originally copper stains, and something you did removed the stains, the copper would end up in the water. Copper in the water and large amounts of bleach tends to result in clear transparent green water. If that is what happened, the correct way to solve the problem is to use sequestrant. If I am right, adding sequestrant should turn the pool blue right away. At this point I think it is probably worth the cost of a good quality bottle of sequestrant to test my theory, but that is up to you. I suggest either ProTeam's Metal Magic, or Jack's Magic The Purple Stuff.
Meanwhile, there are a couple of other problems: foaming, high CYA, and high FC. The foaming and high FC should both go away on their own, though it may take a while. You need to keep working on lowering the high CYA level.
