Exactly, the pond dyes do not contain any type of copper anything in
them to achieve the blue color.......Instructions on the jug of dye I
have says its safe for all aquatic life forms,as well as safe to swim
in, and safe for livestock to drink. Cattle ranchers around here also
use it in their livestock water tanks to reduce algae growth as
well......
