I checked out your pics, the filter inlet pipe (the crud stopper) and the power head look as though they could do with being cleaned with a tooth brush... every little bit of cleaning helps with the health of your tank.
I'm going to suggest that it might be worth you doing a 3 day blackout with your tank, no light or co2 and a big rubbish bag over the the tank. This in theory should kill off the algae.

I'm still going to recommend using liquid carbon as a algaecide.
