jayfeather toilet issues Poop sitting on some black baffle

Try this easy method of cleaning black tank. Fill black tank 1/2 full or half empty of water, add a 20 lb. bag of cubed ice, put down toilet opening, take trailer on a 20-25 mile ride where you turn left and right,make it slush around the tank knocking the crud loose, flush tank with lots and lots of water. Should do the trick. Down side, you may or may not effect your tank sensors but the things never work right anyway. Good Luck and use chemical treatment and always flush tanks with lots of water.
