Is this coraline algae! I was positive it was and then I got into a rabbit hole and idk! My main concern is the green and I just want to make sure it’s not a problem
the stuff on the glass and rocks are all encrusted on. its not like its a slime residue I can't reach the sand to feel it cause the water will overflow my tank
Cyno, a Soft Toothbrush will Scatter it. Coraline, a Soft Toothbrush will not appear to touch it. But, it will start to spread afterwards, in a week or two, after hitting it with a Toothbrush.
