Normal algaecide levels of copper are between. .3 and .6 ppm. Levels above .3 ppm can cause staining or turn hair green. Levels above .6 are sure to. Howver, since you added the copper and are in the proper range you do not need to do anything except MAKE SURE you pH does not climb above 7.8 (and around 7.4 is much safer) to minimize the possiblility of stains on your pool or the people who go in it.
