I know iron is important and is included in the trace elements. I am using Florish right now. I have also read about some people dosing extra iron through Florish Iron or similar products.
I was wondering if you could put a nail in your tank and let it rust away to get extra iron. Or would this over dose, or even be the wrong kind of iron (if I rember right way back form chemistry there are differnt kinds of iron ions).
