"Laterite" is a clay containing high concentrations of ferric oxide and aluminum. It is frequently added to aquariums to sequester nutrients and stimulate plant growth. All of Brazil, and hence, the Amazon basin, sits on a layer of laterite. Furthermore, PhosBan and the corresponding Magnavore product are ferric oxide hydroxide. So, to answer your question.....iron oxide is not necessarilly harmful to fish.
