It does not work in the Black tank, TheFitRV did a really good video on it a while back, look for it on Youtube. Not sure it would help your grey tank either. If it needs a really good cleaning, try using dishwasher detergent, go for a drive, than dump. It does not bubble, and it is designed to break down the type of dish related grease and food particles that end up in the grey tank.
