Bulk Reef Supply PRO Series Mixed Bed DI Resin (Color Changing) - Part 3 - Bulk Reef Supply

Changes from Purple to Amber when exhausted

Cation Mixed Bed Color Changing Resin can be used with any type of RO/DI system that utilizes refillable cartridges, and is great at removing calcium, magnesium, aluminum, iron, and other positively charged ions. Mixed bed DI resins accomplish the exact same task by removing contaminants and delivering 0 TDS water, but depending on contaminants in your water you may want a cation or anion color changing resin for the best results and efficiency!
