Algae On Plant Leaves

Hi all, attached is a photo of the algae on my plant leaves. I was doing a DIY co2, which I thought with the inconsistent levels could have caused that. But I have no switched over to a pressurized system, and it doesn't seam to be getting any better, but slightly worse. I have tried to use my finger nail and scrap it off, but it is very hard and refuses to come off. Any idea?

BBA- black brush algae.
Causes by fluctuating and low levels of CO2.
Reduce lighting to 8hours a day.
Remove infected leaves.
Dose Easycarbo at 1ml per 20litres.
Inject more CO2 (turn your bubble rate up). use the Drop checker method to reach good CO2 levels.

Thankfully, now that I have pressurized, my co2 has been in the "good" and not fluctuating anymore, and lighting is allready at 8 hours. Is there any way to remove it from the leaves? Because I would hate to cut off half the leaves on my Anubis.

Do you know that because you are using the drop checker?

Not really. They wil grow back anyway.
You could stop-dose the leaves with Easycarbo, it may negatively effect the leaves as well though.
