Algae Type?

[gmc1]

Ok.so my 90 litre is running ok.
My question is for the algae that is growing on my back wall of tank.it's a deeper red/purple than the coraline.it dosent seem slimey like cyno but unsure.I always leave the back untouched when scraping.

You guessed it correctly as cyanobacteria. Either that or the lighting is playing tricks on the photo.

I used UltraLife Blue-green slime stain remover. I think there is a marine version too.
