Hi Randy, I'm trying to work out how much phosphate will be removed from an aquarium when you dose a particular amount of ferrous citrate, but I'm not sure which form the iron phosphate will take. Will the oxidation state of the iron change and form iron (III) phosphate, or will it stay as iron (II) and so form iron (II) phosphate? In your article you say that iron (III) is the most stable under aerobic conditions so I assume it changes to this one but I can't find a definite answer anywhere.
Thanks, Pete
