Algae id

[KING KONG]

This algae is growing on my tank glass from 6 months. It is slowly overtaking my tank. It is very hard to clean and is green in colour. I hv tried blackout for 2 week but it was still there. Can someone help me? I tried sponge but it is hard to clean and I hv to do a great hardwor to clean it.

 

[I never finish anythi]

I get it on my glass also . I use a scraper and a magic eraser. Works a treat . Unsure what algae it is tho. I just thought it was some sort of film algae.
