Grey Tank

You do not need to treat this tank every time you dump, but if your gray tank gets an odor the bad stuff usually grows from the top of the tank down. If this happens, you need to treat it with happy Campers (two or three scoops should do it) . Easiest way to treat the odor is to sprinkle and stir 2 or 3 scoops into a large bucket until well dissolved and pour down kitchen sink. Then finish filling tank and let sit over night. If you are moving right away you can do the same, even better by filling the tank to approximately 2/3 full for agitation while traveling and rinsing it when arriving at your next destination.
