No. But what I saw at the micrscope was much bigger than 5um, so I assumed it was algae. The water laboratory sent a picture of a petri box showing the bacteria, and that bacteria colony had a brown color.
Any suggestions about how to get more specific data will be preciated. Also, if you need any more data I have the water analysis with quemical data.
So the sulphur smell is caused by the sulphur produced by this bacteria?
