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.
Zandor Reviewed by Zandor on . 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 Rating: 5
