You will never overdose copper while using any aquarium specific fertilizers.

Maybe, it’s more like using copper medicine.

Thrive C, Easy Green, Florish all contain the same amount of copper.  If you are that concerned, you can always switch to Thrive S, but then you may windup with the situation of not enough copper!

Copper is an essential nutrient for shrimp but In extreamly small amounts.

I've read the stress level for shrimp/fish is around 0.03 mg/l (ppm).  You would have to pump an awful lot of Thrive to reach that level.
