Brunsviken, a freshwater lake in Stockholm, 3rd of May 2025. 600x magnification.

I am still setting up, searching for relatable proper microflora atlases and learning to add a scale bar, etc. But I drop some photos in the meanwhile. If you have recommendations on how to solve these issues, or on any other improvements, drop them in the comments below!
