Ok, I need a little advice. I have often wondered if I need to leave water in the grey water tanks. I have left water in the black tank from day one. But, the other tank or tanks are left dry. Am I in error with this? Please let me know what and maybe why and how you do.
I have always left some water in all tanks just so the seal wont dry up,years ago I was told to empty them and leave then open to "air out" I found that the seals on the valves dried up and had to be replaced,but I live in a warm dry climate.

I have 30 gallon, each, Black and Gray water tanks. After I dump, I throw in one bottle (16oz) of Calgon liquid water softner along with 5 gallons of water. I also throw in a blue tab into the black water tank.
This seems to keep my sensors working accurately. As I travel down the road, it sloshes around and keeps the inside of the tanks clean. I can see the bottom of my black tank, through the commode and it is clean. I even used an inspection mirror on one of my older units and the tank looked clean all around.
When I winterize, I dump both tanks, rinse thoroughly and then dump in 2 gallons of pink antifreeze in each tank. I also throw a blue tab into the black water tank. I also dump the pink stuff down the drains to fill the traps and then put a cork in the drain, just for odor control.
I have done this on the last several RV's that I have owned and it worked well on all of them.

I put water, laundry detergent and some softener in my black tank but leave the gray dry between trips. I have experienced no issues with this arrangement.
