Nualgi Yea or Nay

Anyone every try this stuff? I'm starting to get some hair algae as my Flame angel slowly decimates my clean up crew & thought I might give this a try.

I remember reading something about it on another site where there were concerns about it containing copper. I believe people that were using it also said their algae problems have gotten worse. I stayed away from it and started to run gfo instead.
