ResinTech CG8-H-ID is an 8% crosslinked strongly acidic cation exchange resin with color indicating dye, providing visual confirmation when the resin is exhausted. The resin is supplied in the free base form and is used for water demineralization when used in conjunction with a strongly basic anion exchange resin in a mixed bed or dual bed configuration. ResinTech CG8-H, without color indicating dye, is the cationic resin used in the manufacture of ResinTech MBD-30 mixed bed ion exchange resin.  Ideal for use in mixed bed or dual bed ion exchange filters where ultrapure water purity is desired (0 ppm TDS, 16-18 MOhm-cm), such as demineralized water for saltwater and reef aquariums, drinking water, and humidifiers.

    Create custom resin blends to optimize water quality to your specific needs or operate in dual bed configuration, using our complementary ResinTech SBG1P-OH-ID strongly basic anion exchange resin with indicator dye. Dual bed filters, with indicating dyes for both anion and cation exchange resin, permit visual indication of exhaustion of both resins. Mixed bed filters use an indicator dye for one resin component only, do not provide a true indication of resin exhaustion, and are inefficient. A dual bed filter, by comparison, permits full utilization of both anion and cation exchange resins, improving filter efficiency, and reducing ion exchange resin replacement. When operating in dual bed configuration, we recommend installing the SBG1P-OH-ID before CG8-H-ID to capture amines generated from anion exchange resin. 

    ResinTech CG8-H-ID is a hydrogen form 8% crosslinked gel strong acid cation resin. CG8-H-ID is dyed with a permanent purple dye that changes from purple to yellow as the resin exhausts. ResinTech CG8-H-ID is intended for use anywhere that a visual indication of resin exhaustion is desired. CG8-H-ID is supplied in the hydrogen form.
