OK I know this has been talked about, but I asked pet wharehouse this very question and they stated "the copper used in these pumps is not ionic copper so there is no way they can leach copper in the system" and stated further that "although they can have a higher failure rate, they are safe in a saltwater environment" I currently have a 2100 in my sump, 3 200's for circulation/wavemaking, and a 180 for surface wavemaking. What gives??? are they really that dangerous or could these problems be total tank failures coinciding with rio pump failures (loss of circulation etc.). Replies welcomed!!!
