KH2PO4 and Fe++ and Fe+++

["Daniel Larsson" <defdac at hotmail_com>]

I've just tried this:
Mix a glass of water with TMG/micro achieving an orange/red color
Pour in some KH2PO4.
Notice the colorchange from orange/red to white/tranclucent.
Wait and notice how the haze slowly settles on the bottom of the glass.

This can't be good.

This would mean KH2PO4 is such a "hit" for some aquariums because
the roots get their share of precipitated minerals and phosphorous?

This would also mean P-dosing should not be done in conjunction
with Micros - for example with a syringe by the roots or by
Jobe-sticks?

Please elaborate.
