Some wide field shots under normal tank lighting and microscope shots at varying magnifications + a video through the eyepiece. Some diatoms in some frames for comparison.
Appearance is non-strand like. Just a coating on top of the substrate/rock. Started on one rock and crept on to the sand - now spreading around the tank quite rapidly. Could it be some type of green cyano as it does not appear 'plant-like' at all?
I prepared the sample by scooping a small amount of substrate with the substance on it and some tank water and shook it vigorously for a minute or so. Took a single drop of water onto a slide and placed a cover slip over.
Sorry just to add - it does develop quite a lot of bubbles - more throughout the day so I am assuming it is photosynthetically active.
