Hi, Carl,

Not to hijack this thread but Poolsean said the same thing in another post about green water and copper. I am not aware that copper turns the water green. Of course it turns hair green when it precipitates and it stains blue and green on the pool when it precipitates, but it is not clear to me that it gives you green water while it is still in suspension.

Another aside, "Thank You", for the nice compliment you posted on my pool.
