I have read that article and wish I would have found this sight before I put fish in. Well that did not happen. I live in Wi so I drove up to Dr.s foster & smith. I told them I was just starting up and that the main inhabitant was to be a lionfish. I was directed towards a flame dwarf angel and a orangetailed damselfish. As I have since found out the angle will probably not make the cycle and the damsel will get eaten by the lion. So here I am trying to keep them alive. Under these circumstances would you use it?
