Interesting, so for the lay person, metal testing is unreliable to the point of being useless? So do we just assume because my pool water had been on the acid side and I have mostly copper pipes, I probably have some copper?

To my knowledge, I haven't used any pool products that contain copper. I checked our chlorine pucks and they do not have copper.

I also looks like I left off the first part of my post with my test results. I tend to type in a document and then cut and past so I don't lose stuff if a posting goes wrong. So here it is again;

We recived the Taylor 2006A test kit today. Here's the results;

FC- 1.2 ppm
CC- 0.2

pH- 7.0

TA- 120 ppm
CH- 875 ppm

CYA- 90 ppm
