Spontaneous Generation is an ancient theory for the origin of things: dead carcasses left in the sun produce flies, earth produces snakes, etc....
This belief belongs to the Roman era. Not the 21st century.
Animal life comes from animal reproduction. Plant life comes from seed, runners, spores, cell division, etc. Just sayin'.
Ich and algae, same story: you do not produce ich by stressing fish and it isn't always present. Ich is an animal with a life cycle involving sucking nutrients from fish, like mini-vampires. You do not produce algae if you do not have algae bits. You do not produce cyanobacteria by any process. It's a real ancient bacterial sheet that photosynthesizes and reproduces itself by cell division.
