Maiden voyage success - question about grey water tanks

Other than overall using less water than at home, as suggested above, wash the dishes in a separate wash tub and dump it down the toilet. Extra water in the toilet is always good and the soap helps to prevent stuff from sticking on the sides of the tank so that the gauges work better.

Also, wipe the dishes off with a napkin or paper towel so it takes less water to wash them. And then only was dishes once a day.
