Mixed Bed Resin Cartridge

Premium replacement DI resin cartridge for just about any classic RO unit style and makes for easy replacing of exhausted DI resin media. Perfectly fit for the AquaticLife Classic 4 Stage RO Unit.

The Nuclear Grade Colour Changing Mixed Bed Resin physically changes colours as it becomes exhausted, allowing you to monitor the consumption of the DI resin and know when to change it out. If you use a TDS meter on your RO/RODI system we still recommend colour changing resin as it will let you know when to monitor your TDS meter before the total dissolved solids in your filtered water start to increase. Colour Changing DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero in the final stage of an RO/DI unit.


  • Changes Color from Blue to Tan as the media is exhausted.
  • Cation and Anion resins (H+ and OH-) remove the remaining total dissolved solids (TDS) from membrane-filtered water.
  • 10″ standard cartridge size includes a top gasket for a secure fit.
  • Cartridge housing shape lends itself to efficient water-to-resin contact.
