RODI Reverse Osmosis Filter Replacement Kit – 10 Inch Sediment, Carbon Block, TFC RO Membrane and Color Changing Mixed Bed DI Resin Cartridges, Compatible with Aquatic Life and RO/DI Systems

This Reverse Osmosis Deionization (RODI) Filter Replacement Kit provides a complete 4 stage water purification solution for aquarium RO/DI systems. The kit includes a sediment filter, activated carbon block, high rejection TFC RO membrane, and color changing mixed bed DI resin to deliver ultra pure water for saltwater and reef aquariums. Incoming water first passes through the sediment and carbon stages to remove particles and chlorine that can damage the RO membrane. The Thin Film Composite (TFC) membrane, constructed from polyamide material, removes up to 98% of dissolved contaminants, significantly reducing Total Dissolved Solids before final polishing. In the last stage, nuclear grade DI resin reduces TDS to 0 ppm, producing water suitable for sensitive marine and reef environments. Designed to standard 10 inch specifications, these replacement cartridges are compatible with Aquatic Life RO systems and most standard RO/DI units, offering easy installation, reliable performance, and consistent water quality for aquarium use

• COMPLETE 4-STAGE RODI FILTER REPLACEMENT KIT: This all in one replacement kit includes sediment filter, carbon block, TFC RO membrane, and color changing mixed bed DI resin, delivering ultra pure water for saltwater, reef, and aquariums using RO/DI systems
• SEDIMENT FILTER – EXTENDED SYSTEM LIFE: The 10 inch sediment cartridge removes dirt, sand, silt, and rust before water reaches the RO membrane, helping protect downstream filters and reduce maintenance costs in aquarium RODI systems
• ACTIVATED CARBON BLOCK – RO MEMBRANE PROTECTION: The 5 μm carbon block filter reduces chlorine and organic contaminants, conditioning water prior to the RO stage and helping extend the lifespan of the TFC membrane
• HIGH REJECTION TFC RO MEMBRANE – UP TO 98%: The Thin Film Composite (TFC) membrane uses polyamide material to remove up to 98% of dissolved impurities, significantly lowering TDS before the DI stage for more efficient and consistent purification
• COLOR CHANGING DI RESIN – 0 TDS FINAL OUTPUT: Nuclear grade mixed bed DI resin polishes RO water to 0 TDS, with a color changing indicator for easy replacement. The resin changes to a tan color when it needs changing. Standard 10 inch cartridges Compatible with Aquatic Life RO and most RO/DI systems for a secure, leak free installation
