Microbial swimming swarm of black dots
Question
I found a half drunk Arizona that went unnoticed, when I went to flush it a black liquid came out, I realized it was actually a swarm of what looked like tiny black dots that very quickly swam away from the water and up the toilet bowl, any answers as to what it was?
Answer ( 1 )
That may be some parasites or maybe the bottle was opened/leaked and algae developed inside. Some other impurities can also be predicted but maybe I can answer better if I see the image.
