Possible copper contaminent

[Sever0n]

I just hooked up a phosphate reactor and figured I'd use marc weiss Phosphate silicate magnet and only after I had it hooked up did I realize that one of the ingredients was copper... should I be in panic mode at this point? or does this media have enough binders to keep the copper from being toxic to the corals

Copper is a common additive in trace element mixtures, and this looks to just be a mixture to drive bacterial growth, similar to adding sugar or vodka. I personally wouldn't use it even without the copper, but that seems an additional reason to avoid it, IMO, as I do not know of evidence that our tanks are copper deficient.

I am not a fan of Marc Weiss. A lot of hype in my opinion.
I have had good results with a non iron based remover in the
past.
