Hey, I have the BFS-161 premium RO/DI system(bought Nov. 2008) and i was wondering if it came with color changing resin, what color is it when it is exhausted? Mine still looks black. Please let me know so i can determine if it looks exhausted. Also, did it come with a refillable cartridge on the resin cartridge? thanks, jack

Hi Jack. That resin should go to a light tan when exhausted, but use the color-changing feature as a rough gauge only - trust your tds meter!

And yes - it has a refillable resin cartridge.
