My color changing DI is blue and turns brownish peach. They start to turn from the bottom up.
Never trust the color changing DI always use a TDS meter to measure water coming out of the DI if it doesn't show a 0 reading it is time to change the DI.
My chamber acts similar to yours, when the system is off the water fills to the top of the outside chamber but when I am making water the level tends to hang out at the half way mark.
