I think around 0.3 is when you have to start worrying ... so that test is a little inconclusive, but likely you have a copper problem.

That 4ppm is with no CYA in the drinking water. Since most of your FC is protected by CYA, the active level of FC is far lower than what the CDC allows, even at your SLAM level.My wife has been concerned with all the bleach I've been using. She doesn't think it is safe.
I remember reading a post here about CDC? Recommends that drinking water be around 4ppm? I, in a round about way, explained that to her and I think she is on board.
Jblizzle. Do you have any advice for a remedy? I bet your going to say drain the pool some.

Well, I see that pool looking a lot more blue than before and I will venture a guess that it will end up a good blue color, not a pale clear green that says copper problem.
Does the liner have any sand color to it? Beige stone colors? That might add a green tint to the water. Yellow + blue makes green.
The original poster here says in his first post that he's used a copper system for two previous years. Wouldn't it be easier to drain and replace the water to get rid of all that copper?
My hats off to yall. I tell everyone I know that has a pool about this site.
