Re: [APD] Re: Barr method and Iron

Probably -- not hard to to. There is a trace element mix
called Flourish and then there's a supplement to that trace
mix called Flourish Trace, which is not a general trace
mix. Flourish, which is a general trace mix is a supplement
to macronutrient fertilizing. But Flourish Trace is only a
supplement to a general trace mix.

Flourish has a healthy dose of iron and Flourish Trace has
none. Flourish Trace, is intended as a supplement to
Flourish for special needs, as is Flourish Iron. Flourish
is meant as a general, everything they need trace mix.

And don't confuse any of these with Flourish Tabbs, which
are neither marco nutrients nor general trace mix providers
nor Flourish Trace providers but supplements for a general
trace mix, providing extra stuff for roots.

The really surprising thing, perhaps, is that TMG has so
little iron compared to Flourish, and yet my plants seem to
do as well with either. Others have reported pretty much
the same. Which suggests to me, that Flourish has gobs of
iron and Flourish Iron is needed only in cases where the
powerhead is frequently running all the water past a magnet
;-) or maybe if folks insist on adding iron everyday [or
are trying to amass enough material to build a magnet].

--- Christel Kassellman is returning to America! ---
The Northeast Council of Aquarium Societies will feature Christel, author of _Aquarium Plants_, among its speakers at its 30th Annual Convention. It's the longest running consecutive general tropical fish convention in the country and one of the most fun to attend.
