I had the impression that healthy bacteria would not survive without a steady supply of oxygen? Would enough plants be able to do the job?

I haven't gotten a reply back.
I guess I put a little too much truth in mine, with irresputable proof to back it up, so they couldn't type up some bunch of garbage and send to me.
