1. A display for a water treatment system, said display comprising:
first and second light sources operable to generate light, said first and second light sources being separated by a light source distance;
a graphic mask including a graphic element configured to allow passage of light;
an optical element having first and second light receiving surfaces operable to receive light respectively from the first and second light sources, the first and second light receiving surfaces being opposed by an optical element surface of the optical element, wherein at least one of the first and second light sources being spaced from the optical element surface by an optical element distance;
wherein the optical element includes a mask facing surface adjacent to the graphic mask and defined between a) at least one of the first and second surfaces and b) the optical element surface, wherein light received by the first and second light receiving surfaces reflects internally within the optical element with respect to the optical element surface and the mask facing surface; and
wherein the light source distance is greater than the optical element distance.
