IceCap RO Deionization Resin, 1.25lbs (Single-Fill)

Guaranteed Zero TDS Output: Operates as a high-affinity chemical polisher to trap remaining dissolved minerals, ensuring ultra-pure water for delicate reef ecosystems.

Virgin Mixed-Bed Formulation: Compounded strictly from 100% brand-new, un-reclaimed raw resin beads to deliver maximum ionic capacity and longevity.

Vibrant Visual Color Change: Transitions distinctly from a deep blue/green shade to a light amber/brown tone as the internal chemical capacity becomes fully exhausted.

Foil-Lined Vacuum Packaging: Factory sealed inside an air-tight, moisture-locking Mylar bag to prevent premature air exposure and extend un-opened shelf life.

Universal Cartridge Architecture: Universally sized to pour perfectly into IceCap Smart RO/DI systems as well as standard 10" refillable shells from any brand.
