Biofilm forming on my Ecosphere? What do I do? (I’m referring to that white thing close to the soil)
Most of the bottom part is activated charcoal and gravel. It was going to be a terrarium at first. When I move it around, some bubbles surface. Do I have to remove some of the decaying material or something?

Biofilm is normal and part of it. But you need to add live aquatic plants. A vital key element in an ecosphere.
