I will try it!! I have used Unique on my boats, albeit the holding tanks are easily dumped since they are vacuumed out with plenty of suction that evacuates not only the holding tank but toilets and long sanitation hoses. Even then, I fill the holding tank up twice and vacuum out to make sure the system is fully flushed.
