I've been using New Life SPECTRUM Marine Fish Formula and finally read the the ingrediants...Copper Sulfate...Ferrous Sulfate...Manganese Sulfate...ect

Will theses metals adversly effect my reef tank? Or are they non-toxic?

Copper, and some other metals, are funny things. A little bit is needed for life, while too much is a problem. In the case of fish foods like Spectrum (I use it myself), there is not a problem with the amounts in them.
 
You will notice that copper is listed as an ingredient in most every fish food. Tiny trace amounts are safe and in fact necessary.
 
Agreed, it's one of those funny micronutrients: way too little will kill ya and way too much will kill ya too. The small amounts in food (especially since they should be chelated/bioavailable) should be fine, and in fact necessary.
