Personally I do not use PMDD. I use Tropica or SeaChem's Flourish line. It's
easier for me. It's also a good baseline for comparing notes with other
folks who actually do test their water and try different approaches.
Most of them used these two products, so I have as well. Consistency is
important. So in answering your question, I add all the traces, not just
iron by itself. Some folks, Steve comes to mind and a few others "spike or
pulse" their iron levels in addition to the trace mix. It did not do the
same thing for myself as them but it could be from the softer water also. I
have not looked into it much.
You'll get a number of "methods" that can all work.
Some go for a low PO4, some lower NO3 some low Fe etc. Plant health is what
the biggest issues really is. They grow well and we all are happy. Except
for the algae.

I'm lucky to understand what I mean:)

Ah yep. Well put. Erik's responses and test have been mirrored by a number
of sfbaaps folks. I've tried it out on many folk's tanks. It works. But you
need to get the CO2 right and then move down the line on the nutrients.
CO2-> NO3-> K+-> PO4-> Fe-> traces etc. Set your tank up so that all you
have to worry about are 4 things, NPK and traces. CO2 via a gas tank system
and decent lighting.
