[APD] Help on copper sulphate solution

[Stuart Halliday <stuart at mytriops_com>]

I need to find out if a 1.2% solution of Copper Sulphate in de-ionised water 
will kill any copper sensitive aquatic amphibian creatures in a freshwater 
aquarium?

Can some talented person tell me the microgram concentration of Copper the 
above would have?
