Any pool can have copper. Source water may have it in it. Some pools have copper plumbing. Most pool heaters have copper heat exchangers. If your pH or Alkalinty levels are lower than recommended, then the copper in the plumbing or heater can be stripped out and stain the pool plaster a bluish-green color. Some allgaecides even use copper which will also stain. You should also take care using copper algaecide in salt water pools as they may cause problems with the chlorinators.
