I currently do not own a microscope and I’ve been lucky up till now in my 1 and a half year of owning tanks to only dealt with diatoms until today when I started to get this in my 4 month old tank which is my newest tank. It looks like brown jell as it’s puffy. I want to say it’s a type of Dino but I’m not sure as I don’t see air bubbles or long strings. This is the best close up I can get and it’s on my outflow.
