Gonna look at it today , put it in for the winter . will have the water tested today at leslies

HTH yes it contains copper ,

[vinper]

My water turns green for a few days after shocking it with bleach . I am assumming its copper from some winter algecide . I ordered a culator

[chem geek]

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.

Yes it bothers my wife. I assumed it would subside by swim time

culator has not change to any color , does not seem to have absorbed any metals running it 2hrs a day for last 2 weeks

[chem geek]

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.
