Tim, if you're afraid your algae has resulted from too much iron, don't
switch to Flourish Iron.  That preparation is not a fertilizer per se, it's
straight iron.  A test kit would help clue you in, of course.  Yellow color
is not always caused by iron.  Nitrates would be one area to look at, and
Potassium deficiency can cause the similar symptoms.

Live bearers eat hair algae, as do C. japonica shrimp.
Hope this helps.
