Slight green tint

Then, if Dave S's advice doesn't work (it should work), have your water checked for copper and other metals.

But assume it's algae first that you have to kill before testing for metals.

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.

After looking again in lower light, the pool looks a little more reddish than geen. I live in NC and deal with red clay. The lot next door is being built on andis bare. It was windy this afternoon also. So I am thinking the red dust from the lot next door blew in my pool and is now suspended in the water. I brushed the bottom and a reddish cloud rose up. Should I still raise my chlorine level to 15ppm?

I'd vac the bottom and see what happens....I get the same thing from the street behind our property. Couple gallons of bleach wouldn't hurt if you think you have an algae bloom, but definitely keep at shock level if needed.

A clear green tint to the water can be an indicator of excess copper.
