Tough to remove spot algae ID

[Gordon3883]

Hey all,

I have spot algae taking over my glass. This algae is very hard to remove, I had to use a mr clean magic eraser to get it off. I was gone for a week due to a work trip and the glass never got cleaned. I am trying to get an ID on it as well as some of the spot have fuzz on it. The tank is about 7 months old. Any help is much appreciated!

You may want to look at a scraper with a stainless steel blade attachment.
