    An air stone won't kill bacteria. Don't know why you were told that but that's not correct.
    polishpollack Reviewed by polishpollack on . DWC i am building a 40 bucket dwc system my question is do i put a air stone in each bucket or just a air line(no stone), cause a buddy of mine told me that the air stone will kill all the bacteria(and you will want some bacteria) and recommended me to just put a 8in round air stone disc in the 55gal reservoir and it will be fine Rating: 5
