 Re: Against the advise given.
like you say whether your ammonium goes to ammonia is dependent on your pH too if its way over 7 you could have trouble. But then again it depends how efficiently your microbes are whipping it into NO3. I guess if you have a healthy well-active tank they should cope with it OK as the fish are producing NH-N anyway. You don't need to be particularly concerned about the anaerobics he mentions as you will only have pockets of these areas, after all you have an aerated aquarium, not a stagnant pond! So your excess NH-N should end up as NO3.
If you find something with chelated iron in it that should be the best most-easily- available-to-plants form to get. Not much help really :-( IMHO I'd go with a "proper" aq. fert (or terrestrial version with same specs) and keep an eye on water params, part pH. Best of luck
