I guess if your using CO2,then Iron might not be needed. But for all other setups,aquariums,aquaponics and maybe hydroponics..I tell you gluconate Iron drives plants wild. Seen it with my own two, and half the time four eyes. Glasses.
One more,maybe more than the dose on the bottle is needed for a heavy plant growth. Still,fish are fine and happy. I'm even thinking its healthy for them. Gives them energy.
