I thought the copper issue was behind me since I got it down to 0.2 but I guess thats still enough to cause tinted green hair. Lucky for my daughter its not very noticeable but I need to fix this issue. What does everyone recommend? I originally had over 2.0 when I first opened the pool. I can only assume it was from the previous owner using copper algaecide. I would rather not drain the pool again as it took me over a week to refill half the pool as I am on a well. I have not noticed any major staining in the pool other than a slight shade of tan on the steps but I figured that was from never being properly cleaned. I am open to all thoughts..
