I have a theory

I'm a fuzz confused on that article. I don't see anything there that differs from what is said in this thread here. I mean, it's no secret(to me atleast), that there are countless numbers of microorganisms in water(of all kinds). The nitrogen cycle applies to the planet earth. Grab a handful of soil and try to imagine how many microorganisms there are. These extra micro/macro organisms are really irrelevant unless we needed to take advantage of them. As aquarists, to keep it simple, all we care about are the nitrifying bacteria. Same with the nitrogen cycle that happens between animals and plants. As a gardener. I'm absolutely taking full advantage of bacteria, fungi, and protozoa I can brew up in my compost tea. I'm not trying to dispute anything or bag on your thread, I may just be missing a point. I like facts and all I see is assumptions.
