Hi Matt,
Welcome to TFP!

The green hair is caused by the copper in the algaecide you've been using. Help the wife shampoo her hair with catchup, and it will remove the ionized copper from it. It might to 2 go rounds to get it all, but it will.

If you would like to learn to maintain your pool without using algaecides and phoshpate removers, then clicking on the pool school button is the best place to start.

Enjoy
