Once a month down yer terlet. It's not too spendy.
Actually... I've been told that Rid-X is really not a good thing. Not sure I can back that up right away... but I'll look around.
That's what the septic guy suggested!
He was extremely helpful. I'm going to write a letter to the company he works for and tell them how much I appreciated him. He was respectful, very helpful and took a bit of time to explain the system to me.
I want to make a point of telling them how satisfied I am with the service he provided...I don't think people do that enough nowadays.
