This weird fuzzy stuff has been growing on the back of my wall for a few weeks but when I woke up today it was really long and growing everywhere in the tank. When i took my heater out to scrape some off it was rough and hard and was green.

Can’t really tell from the photos, but rough and hard on the glass is likely diatoms.

Could you take pictures under white light (ex. with a flashlight)? The blue lighting makes it hard to tell.
