This sample was collected from our garden 7 days ago and kept in an open jar of water.
The contents of the jar had separated into a top layer of moss floating on the top, an intermediate layer of very cloudy water and a bottom layer of debris on the bottom of the jar. I have tried to sample all three layers in the pictures below.
