Hiya, my ecosphere has recently developed this brown growth on the walls and I've been wondering if it's dangerous to it in any way. If that helps with anything, I've recently opened it to move the duckweed back into the water, the main plant has been eaten, or otherwise died and is decomposing, and the jar's Backswimmer has died around 2 weeks ago. I've attached a now and then of the jar. Cheers!

Those are called diatoms. They are leftover decay that is concentrating and eventually solidifying. At least that’s how I understand it. It might not be scientifically correct :).
It typically happens after the biofilm came and went. The brown stuff will sit on the glass and will make the jar look like tea even tho the water is clear.

I had a jar like that after I discarded it and ran it through dishwasher three times and it was still brown. So do yourself a favor and wipe it off the glass now.
And if ever possible, add more plants.
