Rid-X

To expand on why I said its a waste; I Googled some studies some Universities did on septic tank care. They said a septic tank has so much active microbes in it that when fresh feces enters the tank, the microbes it it die because everything has been consumed. What eventually damages the leech field is build up of fiber and certain fats that don't decay, mostly from synthetic fabrics from the laundry. That's why you should have it pumped every five years or so.
