I had a *really* base case of red algae in my 20 gallon tank.  Water changes 
did not help.  I added CO2 injection and started adding small doses of KCl 
and KNO3 a couple of times a week.  The algae growth slowed, and then one day 
the algae just disintegrated and fell off of the plants.  This coincided with 
my CO2 going crazy and suddenly dropping the pH from 7.6 to 6.5 and then back 
up to 7.4 in one day.  I don't know if the algae was almost dead from being 
starved for phosphorus and the sudden drop in pH finally killed it, or if 
this was a coincidence.  BTW, this also killed one of my fish.

That was 2 months ago.  I have since switched to a CO2 tank instead of yeast, 
and the algae has not come back.  But if you look really close there is a 
tiny bit of algae on the leaves of slow growing plants.  So it is just 
waiting to make a comeback.
