Hope you don't live with a bunch of blondes. People usually blame chlorine for turning hair green, but actually it is copper.

How would I know if the algae was dead if it doesn't change color?

I am lost when it comes to chemicals, you people are amazing when it comes to that.

But I've vacuumed a few pools in my day .

If the algae comes up very easy and doesn't cling at all, it's pretty much dead.

Merci beaucoup, mon frere!

Generally once the algae dies, the water will change to a cloudy blue.

About the copper--once your copper level gets high enough, then you're going to have staining of the pool with higher chlorine levels, then the care of your pool is going to take on a whole new dimension.....as well as people having green hair and nails, as Watermom noted above.
Copper does have an algaecidal effect, but so does correct levels of chlorine. I personally wouldn't add anything else to the pool that contains copper!
