Anything you add to the water column is potentially algae food.

I've used Tetra Flora Pride for several years, as much for the K as for
the iron.  I usually (not always) use 1/2 the recommended dosage.

As I recall, Flora Pride is intended for use after water changes, not on a
daily basis.  The iron level will drop after you first add it and should
be mostly gone before you add it again.  The average concentration
probably won't be as high as 0.4 ppm.
