Copper is common in pools that use well water to fill. City water usually does not contain minerals but this is not always the case. The bottles they sent you home with are probably metal sequestering agents and will help keep the copper in solution so you cant see it. Keeping your pH 7.2-7.4 will also help.

I do not use well water and have I levels of cooper in my pool. What chemicals did the pool store give you to reduce the cooper level. The pool store told me to drain half the pool and retest.

If your copper level is low (less than .5ppm) you simply need to get your pH down to 7.2-7.4 and use a metal sequestering agent. If your copper is high it may be necessary to drain some of your pool. What is your copper level? Copper is sometimes found in city water as well and is also in some algaecides. If you use too much of a copper based algaecide this can cause higher copper levels as well.
