I find algae growth is dependent on many conditions: light, nutrient levels, circulation, overall cleanliness and maintenance. I think the answer to your question is it depends upon how much of those fertilizers that you add.
The website appears to be 'down' at the moment, I will try to read this thread later.
Google translate :
My aquarium is a bow front with external power head filter (1000 liters per hour), I do 30% water changes weekly.
I talked with my friend in the USA its hard for him to bring bottles (and powder)
so I cant get any of the Seachem products or any dry ferts.
