Seacosphere full of life >3.0% salinity

These tiny red dots are Tiggerpods. This jar feels more alive than some of my freshwater ecospheres.

Full of life. Worms, tiny copepods and a few snails. It's around two months old. I put the snails in there one month ago and they look healthy. Some parts of the algae (Caluerpa) are dead but it's growing fast. I hope so much for the snails to lay eggs.

Edit: it already survived temperatures above 30°C so it seems to be pretty stable so far.
