You don't need to go to the expense of dosing macro nutrients. If you change half the tank water every week and feed your fish a balanced diet, then you're providing all the macros needed.
The macro nutrients are needed in large quantities, while the micros are sufficient in smaller amounts. That works well, because the macros are replenished by large and frequent water changes and from the fish wastes. So, that's the reason for a varied diet for your fish.
The micros do need to come from a commercial source in dry, granules or liquids. Iron is one of the micro nutrients.

BBradbury,How can you make this statement without knowing anything about his tank????
To answer your question, Zavikan, you can dose iron daily. You just can't mix it with kh2po4. Doing so will form iron phosphates which are useless to our plants and a waste of ferts, so to speak. It could also make your water cloudy...
What you could do is add the iron to your micro mix and dose half of your normal dose daily.
This is what I do anyways... Works great actually.
i was under the impression that you can't get potassium frm fish food and sometimes water changes either.. food and poop only provides nitrates after cycle and phosporous
Iron added with mono potassium phosphate (KH2PO4) will cause the precipitation of both iron and phosphates, removing both from water column, as they react forming insoluble salts. ALso (needs to be confirmed) I suspect these precipitated salts to form the film on the surface of the water. As it seems every time I add iron and phosphates without sufficient time interval in between I get the surface covered with the thick layer of some substance. It might be just a biofilm, or something else, however. Anybody else is observing this kind of thing?
BBradbury isn't a troll. Just keeps giving out his/her philosophical leanings and experiences with BBradbury's own tanks.
There's many different ways to build a planted tank system depending on the goals. BBradbury's ways work well for his/her setup, but not for most of us IMHO.
I really think BBradbury means well.
