I don't think SeaChem is involved with Spectrum folks
anymore.  Nonetheless, they told me some time ago that the
copper was a trace amount and trace copper is good for many
living things.  I never noticed it hurting my shrimp, even
after using it for a year.  Although they were and remain
as steathy critters can be -- the shrimp, that is, not
SeaChem.
