I'm not sure what exactly I'm looking at. It's not the typical Cyano.. or Dinos. If It's something already visited, I haven't found It yet. As you can see in the last pic, it does have a few nitrogen bubbles... however the overall texture is more like felt than snot. Not slimly at all. I DO have some small patches of traditional dino that appear on my LR occasionally, but typically stays isolated to the rock.
