Default Black Alge?

I'm having a problem with what I would call 'black alge' on my plants
and driftwood. I have a 55 gallon discus planted tank, 2.4 watts/gallon, pH
6.2, temp 84-85F, GH 75ppm, KH 120ppm, 0 Nitrite and less then 20ppm
Nitrate. I feed the plants the usual Flourish supplements every few days.

This stuff is slimy and covers the leaves and back of the tank. It's
almost black and I clean it off with my fingers. I keep the lights on for
no more the 12 hours. Any help IDing it or suggestions on how to get rid of
it would be appreciated. Thanks!
