If you're saying that you dosed your FO with copper, that really is not a good option. Copper will effect you bio-filter considerably, and, because it is not so easy to remove from the tank, that contamination could be long-term.
Hypo, however, would work well on a FO tank.
I hate to slightly disagree with Beth. I have found her information to be extremely valuable and correct; ever since relocating and taking a more "researched', rather than "trial & error" approach to our hobby/addiction. However, I do not think Cupramine copper will do significant damage to your bio-filter. Cuprimine's manufacturer, SeaChem told me basically, "it will do some damage to the bio-filter, but no a major wipe-out". I've found SeaChem's tech support to be excellent on several topics, in spite of their obvious desire to defend their products. I (I know the contraversy) treat all new fish with Cupramine and a de-wormer upon arrival in QT. On several occasions since relocating, I have had enough new fish in QT to be considered "over stocked" in my 55, well cycled QT. I have never been able to measure any significant increase in ammonia, in spite if the Cupramine present. Sometimes a minor spike after introduction, then normal the next day, showing that the aerobic bacteria are reproducing normally. I have also found Cupramine very easy to remove, assuming no LR or other porous material is present. SeaChem Cuprisorb works better & faster than carbon and can be regenerated. If copper stresses fish more than hypo, I haven't seen it. However, I suspect that may be true. What I do know, is that copper stresses ME less. This will drive some folks nuts; but my fish's main function is to make me happy. Of course, when they're healthy & thriving---that makes me very happy!
EDIT: After re-reading, I see I was referring to a QT and Beth a FO tank---with substrate and rock, etc. My comments apply only to tanks without porous stuff, like substrate, rock, skeletal coral, who knows what else..
