I don't have the exact measurements of your ingredients but I'm thinking it was close to a cup of Calgon and a cup of Blue Dawn. Fill the tank approximately half full with water and travel a hundred miles or so. This may clean the black tank out but I'm totally sure. I personally use Happy Camper in all three of my tanks (black and two grays) and feel I'm getting the best job I can in cleaning them. You will never get the black tank totally clean because there will always will be some gunk in the bottom of the tank unless you use some sort of pressure wash on it and flush it 15-20 times and then still no guarantee on it them. If you are worried about your tank probes and their readings, you might as well forget that unless you go with an external reading system where nothing can get on the sensors.
