I know this has been brought up many times but I just thought I would share my findings. I found this link in a thread and gave it a try. It was adding 2 cups of water softener and one cup up laundry detergent to the black water tank and two cups of the softener to the gray water tank. Well it works. My censers have never worked right censers I bought the RV. I put the stuff in the tanks about 2 months ago and we went to my mothers house this week for a few days and today I went and emptied the tanks. when I tried the lights on the dash they both showed empty. It's the first time they didn't show full. And I noticed when draining the tanks it even had a almost good smell to it.
