Sounds more like BBA (Black Beard Algae). In my experience, it's primarily due
to excess phosphates in the water. Excess iron normally shows as long stringy
green hair algae.
SAEs eat it quite well, and Dwight reports that the American-Flag fish also eat
it. I saw my japonica shrimp eat it a little, but they wouldn't be able to
eat enough to make a real dent.

No, more light probably wouldn't do it. You need to resolve why your plants
aren't using up the phosphates.

The zero nitrates is a key here. If the nitrates really are zero (or at least
very low), then the tank is "nitrate limited". That will stop the plants from
growing, meaning all the other nutrients in the water (like phosphates) are
available for the algae. You might want to consider adding nitrates (using
KNO3). That will allow the plants the grow more, using up the phosphates. The
idea is to make your tank phosphate limited, at which point algae will be more

As long as Kent Freshwater doesn't contain phosphates, it's not the cause of
I've got an article on my website discussing KNO3 dosing.
