I can only contribute what works for us...
After dumping the black tank, I then leave the black valve open and proceed to dump the gray tank.
Afterward, I hook a hose up to the Black Tank Flush inlet (built in on my rig) and flush the black tank well until the water runs clear. (I have a clear, Sani-Flush adapter on the head end of the waste hose).
I then close the black tank valve and hook the hose up to the Sani-Flush and back flush the gray tank.
Then, I'll close the gray tank valve and set the Sani-Flush to rinse the hose out for a little while.
In the meantime, DW mixes 5 gallons of water and Calgon Liquid Water Softener to go into each of the holding tanks. She then dumps 5 gallons into each into each of the holding tanks. That clean "soft" water will stay there while we travel and through the next trip. The movement will cause the water to slosh around and keep the inside of the tank coated with "soft" water which will resist anything from sticking to the inside of the tank(s).
We also use a "green" additive to the black tank and a liquid deodorizer to the gray tank.
We've been using this method for the past 12 years and two rigs and we have yet to experience any problems with our holding tanks.
