Abstract: A toilet bowl sanitizing tablet that is constructed of solid, clear or white cleansing and/or deodorizing chemicals and has a smaller color core embedded in its center. This device when placed inside the toilet tank will slowly dissolve into the tank water, thus sanitizing the toilet bowl with clear, clean water with every flush. After weeks or months of use when the outer tablet has dissolved down to the center color core it will release its coloring agent to the water, thereby notifying the user the tablet has reached its depletion; eliminating the need to mark calendars, count flushes or periodically check inside the tank.
