Default Black beard algae problem

I believe this is the type of algae I have. Someone posted a picture of it
a while back, but I can't find the post. It is thin, stringy, black, and
about 2" long.

It is completely taking over my tank, and I am at a loss as to why. I
thought I had a micronutrient problem, so I upped the dose of TMG. The
plants are growing SO fast, that I wonder how the algae can keep up. My
echinodorus bleheri was 5" tall a month ago. It is now 15" tall. I also
have Hygrophila Rosanervig which I have to throw out about 6" a week.

This dang algae is completely covering the echinodorus, the hygro, the java
fern, and the java moss. I keep pulling out all the affected leaves, but it
doesn't stop. The tank is a 20 gal, so I can't get any SAEs.

ph - 6.6
kh -2
light - 55W PC on for 14 hours/day

Any ideas?
