The jar has been placed outside now for 3 weeks. Weather is uncommonly warm and no rain. Water level dropped several times and was re-filled with bottles still water, tap water (pretty stupid, because it’s full of chlorine) and sparkling water. It never fell below 50% of the volume.

A water sample was collected today from a freshwater flowing lake (particularly clean these days), together with a small clam, algae and muck scraped-off a semi-submerged rock.
Sample contains oligochaeta, nematodes
