Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying. We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for.
