Safe for a mixed tank - Seachem MarineTrace ?

[GuppyHJD]

Hello,
I recently had an ICP test done and the results showed I needed to increase my potassium and selenium, along with a few other minor elements.
I saw on BRS that Seachem Marine Trace had those components so I ordered it. When I read the bottle for the dosing information, I read that Marine Trace also has 0.032mg/1 gallon of Copper. Not wanting to kill off my corals and CUC, can I used Marine Trace?

Copper is necessary for living things and that small amount won't do anything unless you dumped a massive amount into the tank. I don't know of any complete trace bottle or set that doesn't have some small amount of copper.

It should be fine. There are plenty of trace element products, so go with the one that you trust.
