Brown Algae out of control!

I seem to be having a problem in my tank.  It is a 20 gallon tank that I set
up about a month ago.  I planted several plants, including Ludwigia, Bacopa,
and some Hair Grass.  I added a DIY yeast system, and built my own hood,
with three 15W lights (a Triton, a Grow-Lux, and a Power-Glow, 45W total).
I even started adding Kent's Freshwater Plant micronutrients.  The pH is
7.0-7.2 with CO2.

Still the plants refuse to grow.  They grow, but very very slowly.  And I
don't get the bubbling on the leaves that I hear about.  Even worse, in the
past week or so, I have gotten a brown algae invasion on my tank.  It is
creating a thick layer on the sides.  I cleaned the front glass on Friday,
and its already starting to regrow by Monday.

My fish are:  8 cardinals tetras, 5 rummy-nose tetras, 3 GreenGold Cory's, 3
Cory punctatus, 2 Algae eating Shrimp, a Singapore Shrimp, and three
swordtails (added a day or two ago).  Im thinking of getting some
algae-eating fish to combat the algae.

My first question is why aren't the plants growing?  Am I doing something
wrong?  Is the bacteria sucking up the CO2 and nutrients?  I thought I was
getting plenty of light with 45W, but I've read that brown algae means I
need more light.  Second, why so much algae?  Too many nutrients?  Will
Hillstream Loaches or Flying Fox SAE's get rid of the brown algae?  I prefer
to avoid Oto's or Pleco's.

Thank you all.
