I've seen/read/heard or guessed, that most red plants, almost require loads
of Iron in the water...

true or false?

The answer would be false, their iron content is the same as green
plants.
"Eat your reds"..........hehe.

Color has a few parameters that influence it. Our preception of color
is part of it also. Generally high traces/PO4/CO2 and low NO3 gives
the best reds.

But do red plants need more iron than green plants?
Nope.
