Which fertilizer plants can be used in a shrimp tank?

I use Tropica Aqua Care with Cu 0,006% - is this something shrimp can be damaged?

basically nothing can be assured to be safe. you might use something, and its fine for a while, then everything dies. but your neighbor might use the exact same thing and everything's fine. Personally i don't use any ferts. Just shrimp poo. and my plants are doing OK. Not great, but they're not dying either.

I used something by sera for a while that had about the same amount of copper in it, but have since stopped. My plants don't seem to have suffered at all.
