I have had my tank for about a year little more now and I get brown hard encrusted algae which is more green/brown than brown, i figured its normal but this looks like A LOT more than what I get. Mine gets in the scratches of my glass and wont come off with my magnet cleaner. I have to use Mr. Clean Magic Erasers to get the algae out of the scratch marks. Are your parameters in check? Can you get it off with a regular cleaner? Does it look the same lights on / off and does it receed at all after your scrape it off? How long untill it grows back?

i get that down by my sand bed where i dont scrub the glass as to not stir up debris. i take a glass scraper to it once a month.

Be looking like a form of Green Dust Algae to me.

 

[mr mixy]

it has to be scraped off with a credit card and still is hard to remove

Yea, Green Dust Algae. Seen it many times before, it acts like Coralline, hard to get off the glass but its not Coralline.
