You are welcome.

Years ago, before I knew anything about pools, my blonde hair turned green. I was on my honeymoon, walking down the beach and my husband said, "your ponytail is green!" He was right, green as seaweed. I went to a salon and the girl put something bright red on my hair (about as scary as seeing it green!) that fortunately got the green out. At the time, I thought it had turned green because the hotel pool had too much chlorine in it. Now I know it was because there was copper in the water.
