My leach bed is not absorbing, we have had a lot of rain,a septic person said I need a new bed. I looked into a system called Aero-stream. Apparently it pumps air into the septic tank to kill the anaerobic bacteria, and allow the good bacteria to grow and eat up the sludge in the system and the leach bed. Has anyone had experience with this?

I have no experience with that, but your leach field was designed around how easily your soil drains. Yours has failed. I saw a lot of that in Truckee, Ca in the early 80's. Everything worked in the drought However, when the drought ended and normal rainfall resumed, a whole lot of systems got red tagged. Yours would have been one of them. Sorry, no easy answer here.
