That's a surprise for me... I remembered reading somewhere that Flourish 
itself did not contain any iron itself. Maybe I was thinking of Flourish 
Trace? Hmmm.

I see in my own tanks a very big difference if I neglect iron dosing -- and 
the difference is usually noticeable pretty quickly. I find horn wort seems 
to be especially sensitive, with growth slowing noticeably within a few 
days of low iron levels.
