My First Pool - 0.2 ppm copper reported

[PoolDoc]

Don't worry about the copper. Few tests -- and no teststrips -- can reliably measure 0.2 ppm Cu (200 ppb).

Anyhow, brown is not copper. It might be iron, but it's not copper. Put a vitamin C tab on one of the step stains -- if it clears a small area, it's iron.

Hi, Tim, and welcome to the Pool Forum!

Thanks to both of you. I'm just waiting for my test kit so I can get a handle on everything....
