RE: [APD] Removes "heavy metals"?
I believe the chelators have preference for the heavier
metals. And it's only enough to grab ppb not ppm. But in
any event, if EDTA is the chelator, it breaks down from UV,
such as you might get from sunlight or fluorescent lights.
But I'll bet the plants can grab it eventually anyhow.
Chelated iron doesn't seem to keep the plants from getting
