Zandor....What about beneficial bacteria and airstones?

How about this question fellas.........

We all know the benefits of beneficial bacteria additives and supplements and what it does for reservoirs and root systems. We know that airstones and aeration in your reservoir keeps things fresh like an aquarium. But how about the two together????
Can well aerated reservoirs prohibit (act negatively towards) the life of beneficial bacteria? Does beneficial bacteria suffer from elevated amounts of oxygen from bubblers and airstones? THey say that the airstones prohibit algae, fungus, bad bacteria, and all that yucky stuff. It seems to me that the good bacteria may struggle to stay alive too with all that active air bubble circulation.
I would think that a bubbler system with constant air bubble action in the reservoir, or an aeroponic system would negatively effect a beneficial bacteria supplement if they are in fact sensitive to oxygen content. Maybe in an Ebb n' Flow there would be a better chance for the bacteria to establish itself in the root system in between floods.

Does anyone know if good bacteria thrives or suffers in highly aerated reservoirs?

Well I assume karmaxul has done more research then I have on beneficial bacteria additives. I do know big growers who swear by beneficial bacteria and they have water chillers keeping the temp at 65-68f at all times and the air stones are in each bucket. Some even keep air stones in the res too. If beneficial bacteria additives were sensitive to oxygen then what good would they do for Hydroponic gardening is my point. The more oxygen the better for the most part in hydro. With a re-circulating system many don't use air stones but just falling water at each step to oxygenate the water again. Moving water will also add oxygen as well.

I am just using logic here and I have not given it much thought myself. I have used them a few times but I change my res completely about every 3-5 day's anyway so I don't really use them anymore. But when I was growing KBS full time I did use GH subculture and some fish bacteria for young roots.

H²0² will kill your beneficial bacteria additives and there is some type of Ph up and down that will kill them as well.

1. Beneficial Pseudomonads
1. a. Specific species of beneficial pseudomonads that should be present in any soil, compost or compost tea will be identified and enumerated.
2. b. If the beneficial species are lacking, we can tell you which inoculum to go buy.
3. c. Most plate count labs do not differentiate disease-causing pseudomonads from true beneficials. If you have high numbers of pseudomonads, other services canâ??t tell if they are beneficial species or disease species. Now you have a way to tell.

2. Beneficial Bacillus species
1. a. Specific species of beneficial spore-forming bacteria, typically Bacillus species, that should be present in disease-suppressive conditions, specific insect-pest bio-control species will be identified and enumerated.
2. b. Most plate count labs do not differentiate the beneficials from the neutral spore-forming bacteria, and thus you donâ??t know if a high number of spore formers is a good thing or not. Now you have a better source of specific information.

3. Nitrogen Fixers
1. a. Specific species of true nitrogen fixing bacterial species will be identified and enumerated.
2. b. Plate count labs cannot differentiate nitrogen-scavengers from true nitrogen fixers. People have been mis-lead about the presence of the right N-fixing bacteria being present in their soils, compost and compost teas. Get the real and accurate information! Do you need to inoculate your clover with Rhizobium? Or do you have plenty of free-living N-fixers that improve most crop yields 5-30%?

4. Actinomycetes or Actinobacteria
1. a. These bacteria are quite beneficial for plant species that require strongly bacterial-dominated soils, such as brassica, kale and cole crops.
2. b. Actinobacteria are NOT desirable around conifer roots, nor highly beneficial for most VAM plant species, since they often inhibit ectomycorrhizal and VAM species
