    The algaecide probably had copper in it. Though copper kills algae, it can also turn water green, stain pool surfaces, and tint hair greenish as well. What was the specific manufacturer and brand of the algaecide?

    Yes, turning green after adding a lot of chlorine is the copper. It's mostly from the rise in pH upon chlorine addition. As the pH drops back down, the green may fade. We've had mixed reviews with the CuLator -- it works for some but not for everyone -- so be sure and report back what happens in your pool. We don't have enough reports to be definitive about that product.

    It doesn't always change visibly on the outside. If you have a metal test kit you can see it the concentration in the water has dropped. Eventually, you can take the CuLator out to replace with another and can open up the old one to see if anything is visible. Or contact the company to see what they think.
