Smart Reef^TM +DI (Nuclear Grade DI Color Changing Resin)

1.25 lbs of Resin sealed in a mylar bag to prevent prematurely depletion.

+DI resin color changing is obvious to see. It changes from blue to brown. Some other color changing resins just change shades of color and are hard to determine when they are depleted.

Once the color starts to be mostly brown, use a TDS meter to determine when it is time to change.
