So I got it unclooged. I poured a quart of digest-it ($40) (the bottle is a gallon) into tank with 2 gallons of hotwater.closed tank first. Let it sit 24 hrs per directions and then stirred it through toilet. Directions said to drain tank but it still looked a little thick so I added some more water and dI gest it and let it sit a few more hours and then emptied tank. Closed tank, filled with water and emptied. I didn't that twice and then shut tank valve and added a gallon of hot water and added 4 Oz of digest it per directions. Good to go. I think it would have worked without adding the second dose after the first 24 hours. Oh, after I added the second dose and letting it sit I filled with water so it would drain better. Thanksallot for everybody's input.
