Twice a year:
-Empty gray holding tank and close tank.
-Then mix four tablespoons of Happy Campers Tank Treatment and a gallon of water.
-Drain mix into tank.
-Finish filling with fresh water until you see it coming up into the shower drain.
-Let it sit overnight.
-Empty in the morning
Very smelly stuff tends to grow on the top of gray tanks and this will clean it off.
