My point being that with that specific bag I’m using there’s no proof it contains live bacteria since the bag I had from years ago didn’t have an expiration date or pull date therefore no clue how old or still viable plus has anyone done a DNA test or confirmed where exactly taken and guarantee it’s always taken from same locality?
Yes - that's exactly what happens; the tank (like all ecosystems) finds a balance between the dominant species.
In our tanks, this seems to generally be thought to cause tank maturity/stability.
The microbiome in our tanks literally changes over time and seems to converge to a similar point/mix of bacteria for most tanks (discussed in the thread linked below); this convergence does provide a more stable microbiome over time.

I've meant to start this discussion thread for a while... so here we go. Reef hobbyists have a lot of ideas about biodiversity and what it means in a reef system. A lot of these ideas (mine included) are reasoning from personal experience of myself and others, and how we think it ought to work...www.reef2reef.com
I think there is a lot of marketing pushing for the constant addition of nitrifying bacteria. Quite frankly, if nitrification is occurring and there are no issues, who cares what species is doing it? Personally, I see no added benefit to purposely dosing bacteria on an established system. I'm sure there is some transfer as new corals, fish, etc. are introduced.

I was under the impression they were cysted bacteria; activated by h2o. The powdered bacteria are this type I believe; this is how I have it at least.

Never heard of that but I know from experience of daphnia showing up in tanks I tote down to the glass and washed with tap. Last want build had pods show up before I added anything other than bottled bacteria and ammonium chloride. Makes sense bacteria would also exist in a dormant cyst state but are those what we are talking about or just nitrifiers.
Diversity to me is the microfauna found on live rock which goes beyond just that cycling a tank.
I was trying to wrap my head around bottled bacteria, live sand, shelf life, etc and that's what I came up with. Makes sense. Could be one type though, or not, no idea. Nobody's releasing thier species info. Even of they did what would we do with that info. Hold the bottle up and nod "yup, that's in there" "I concur"

Just watched a video about n pH where even Hanna was question. Exactly how do we know it’s accurate? Just because it’s digital? All off what the manufacture claims? It is what it is

It is damp and not sterile, it is live.

To the OP… what if what you are “pouring in” is not diversifying anything, but rather acting as a prime food source for another species, allowing it to dominate.
As other people have mentioned, without testing AND correlation of those test results to tank health (or whatever it is you think is the benefit) what is the use?
