EXCLUDING VAT DI Resin 5 liter Bag Changes from Blue to Amber when exhausted Anion Single Bed Color Changing DI Resin is great for people that want to be more efficient with their deionization resin usage. Single bed resins do require the use of a cation and anion resin followed by a mixed bed resin, but produce much better results and are much more efficient! Deionization Resin Reverse osmosis systems can remove up to 99% of contaminants from your water, however, they can never remove 100% which is the overall goal for reef tank water. That is where deionization (DI) resin comes into play, by taking place as the last “filter” of a RODI system after the membrane. DI resin is ionically charged as either a cation (+) or anion (-) to exchange hydrogen or hydroxide molecules for contaminants like phosphate, silica, nitrate, sulfate, aluminum, iron, calcium, etc allowing you to achieve 0 TDS water for your aquarium and help eliminate any possible water quality issues. You may or may not know that there are multiple types of DI resin available from mixed bed to single bed resins that you can use depending on what the specific goal is for your water and what is in the water after the RO membrane.
