Copper Sulfate is that bad?

[Tank2379]

I just started using this yesterday Spectrum Thera + A for my Onyx Clowns and Tang they love it by the way also my Mandarin which is a surprise. But anyhow I was looking at the Ingredients and one states Copper Sulfate? Would that be bad let alone be bad for my Corals?

it's either insoluble or at such a low quantity it's irrelevant. Even NSW has some copper in it.

When I was staring out in this hobby my clown got Ich so I dumped some RidIch in the tank(which contains a sh!t load of copper) and it killed eveything you learn from mistakes, but that's why we have so many good people on this site to help. Never used that food so I would not know but if it's for salt water it is most likely safe
