hey Sixty, Believe it or not, I started with analyzing Vibrant from a bacterial perspective (as part of a larger look at a number of bacterial products). I didn't post much about it because it revealed nothing interesting or explanatory. Vibrant didn't do anything important to P or to the nitrogen economy. It didn't process ammonia and it didn't make NO3 disappear etc. If you want to do those things, get nitrifiers or feed carbon.I would of explored further the bacteria options, technically if there is a strain that would utilise nitrogen sources as other utilise carbon that could lead to macro algaes lost or stall some of this algaes will prefer nitrogen sources to nitrates.
I also cultured up all the common saltwater bacterial products I could get my hands on including vibrant and pooled the results and shipped them to aquabiomics.
I posted the results in another thread, and here you can see the full report of all the identified strains.
There's nothing revealing there. No bacillus murderchaetomorphus or any other fictional algae-eradicating bacteria and as @Dan_P referenced, difficult to find any evidence of such a thing even existing.
One thing that the aquabiomics data might suggest is that if you feed sufficiently rich food to whatever comes out of bacterial product bottles, you can grow stuff. But there's no guarantee what you grow would be relevant. Many of the top strains detected are things that have no business in bacterial products.
...and that is kind of an answer to your question, here....
since the cultures for a bona fide bacterial product (MB7), a known algaecide (algaefix), and vibrant all cultured up similarly - it tells you that this test is limited because it can't distinguish bona fide bacterial cultures from random contamination. Which helps explain why the aquabiomics data is a mix of useful genera and things that have no business there.This test raises questions that not been answered yet? What is inside the vial that made the water cloudy
Randy and others are too nice to say I contaminated it, but the short answer is that a small amount of random contamination is completely consistent with all the data. NMR that shows no sign of bacteria, no centrifuge pellet, no detected biologically digestible organics, and yet responsive culture-up to very rich food.As I see it they had similar results to a bacteria based product that contains dormant bacteria.
feel free to explain the similarities.
Contamination could have happened at any point during or before addition to my sample tubes. Could've been in my (previously sealed) syringe, could've been in the transfer from bottle to syringe, could've been during my earlier usage of the bottle, could've been introduced when I broke the seal or in the cap that's not sealed, or in the bottle previously before I got it...and on and on up the production chain.
Showing that an algae killing product's actual algae-killing power was due to its bacteria would require such bacteria existing, finding published evidence of their existence and activity against the wide range of "algae" to match the product effects, require finding those bacteria in the bottle, and doing genetic testing more sophisticated than aquabiomics to confirm exactly their identification, and demonstrating that they can do something in saltwater under aquarium conditions.
Meanwhile, the um... actual algaecide that's been used to kill algae and has been registered in the U.S. for 50+ years is right there in the same bottle staring back at you.
Makes the whole bacterial discussion just silly and moot, right?
