I added it for completeness. Our tap water contains trace amounts 
to start with and I added enough to my PMDD to get 0.05ppm for 
every 0.1ppm Fe. My plants must not use a lot, because it 
accumulates to ~0.5ppm. I never see it get much higher. Now the 
stickler: I test my water at work on an ICP spectrometer, 28 metals 
at the time. It sure does take the guess work out of water changes. 
Plus I get NO2, NO3, PO4, SO4, NH3, Cl and CO2 at work. Once 
a week gives me a gracious piece-of-mind. Sorry I couldn't help
