Will Flourish Excel and Flourish Trace kill snails and shrimp?

ILOVEBETTAS

It's Cory Lover's cat!
Just wondering, because in my nano planted was going to use Flourish Trace and Excel but i don't want my inverts to die.
 
I don't know what the difference between Flourish Trace and normal (just) Flourish is, but I use Excel and plain Flourish in my tanks with ghost shrimp, cherry shrimp, red ramshorn snails, pond snails (wish they'd die), and apple snails (brigs). No deaths. I've been using these for several months, and for the past couple weeks have been tripling the Excel dose to fight beard algae. Still no deaths.

Plain ole Flourish is trace nutrients, supposedly, so I'm unsure of the difference in ingredients, but they must not be the same.

Does trace have too much copper?
 
I've heard from many people that copper kills inverts. Or do you just mean that that amount of it won't kill inverts?
 
I've used ferts with no probs in my rcs tanks u should b fine as long as u have enough plants to use up the ferts.
