Can't figure out why my water is green

[Kcas0772]

Wow, thanks for such a detailed explanation. It may takes me until tomorrow to do the test, I will have to make a trip to the store this evening for some of the things I'll need.

Two questions in the meantime.
First, if it turns out that I do in fact have some metal in the water, but then we do the tap water test and that now comes back fine, is there a chemical that will fairly quickly clear this up, or is it better to drain and refill pool? Also, curious if any of the readings I listed in my first post from the pool store shed any light, like the copper/iron reading or the calcium?

Thanks,
Kevin
