Planted tank with inverts?

How much copper? Ferts usually have only a trace, not enough to harm most inverts. I don't think I'd risk expensive CRS etc or some of the newer snails but RCS, yeah.
 
I have cherry's and yellows not in same tank and dose ferts don't see any harm but then i also do weekly water changes so levels wont build up
 
All ferts have some Cu in it, but it is fine for inverts. It is trace amounts that the plants use, so your inverts will be fine.
