Black algae and hydrogen peroxide?

I have a 20 gallon community tank that has been invaded by a tough,
fiberous black algae.

The tank has a reverse UGF powered by a Fluval 200 filter. It
contains 13 smallish fish (5 Panda corys, 5 serpae tetras, 2 khulli
loaches and a small plecostomus). I only feed once a day and they
clean up all the food. I change the filter floss in the Fluval every
couple months and it's never nasty, just a bit grey and not at all
slimy. Temp is around 76F.

I don't kow where the black algae came from, but I wish it would go
away. I looked around on line a bit and found several references to
hydrogen peroxide as a cure. Has anyone tried this cure? Should I?
If so, what's the dosage? Any other ideas?

Thanks very much for any help.

Sounds like you're real close to being overstocked. What are your water parameters?

I found This bit about the use of hydogen Peroxide as a spot treatment for BBA. Never tried it myself.

Many of the commercially available "algae-destroyers" will kill it, but most of them will kill aquatic plants as well.
