Stopped by a friend's today to help her with her Intex pool that went green while they were away for a few days. She asked me about using algaecide, mentioning that they were swimming at a friend's pool and they claimed it cleared theirs right up.
Me: "Well, PolyQuat can work if you want but it is more of a preventative after you get it cleared. I don't recommend copper algaecides. Copper is a preventative and can kill algae as well, but you know what else it does?"
Her: "Does it turn hair green?"
Me: "Yep, how do you know that?"
Her: "We all had green hair after we left her house. I had to get special shampoo to get it all out."
Me: "Yeah, stick to chlorine, that will clear this up. Just stay on top of it."
Just amazes me the pains some people will go through to avoid actually maintaining their pools properly.
