It honestly shouldn't be a problem.. Its only free copper that can cause a problem, the type in your fertiliser should be chelated, but for general info, I just checked exact measurements for free copper...

Dangerous level of copper :
-shrimps is 0.03 mg per
-algae and bacteria is 0.08 mg per litre.
-some fish, snails and plants is 0.10 mg per litre.
