Hi,
In a webshop I stumbled upon a nice looking plant, Mayaca fluviatilis. After ordering it I read that it's a very good indicator for lack of iron in the aquarium. Of course then I realized that in the pure RO aquarium there won't be much iron, so the plant probably won't do too well. Is it safe to add a little bit of iron for the plant? Or would that be stupid after first taking out all the minerals using RO?
