Packaged in vacuum-sealed mylar bags, it guarantees freshness and longevity, while the color-changing indicator provides a visual cue for replacement. Perfect for all aquarium types, this resin is your go-to solution for crystal-clear water. ## Description Product description Kolar Labs Color Indicating DI Resin for Fresh and Saltwater Aquariums Kolar Labs Color Indicating Deionization Resin is the perfect solution for aquarium systems and other applications where ultra-pure water is a must. Our virgin nuclear grade deionization resin is a mixture of anion and cation gel type ion exchange resins. The mixed resin is prepared from component resins which have been manufactured with the highest degree of purity for drinking water applications and converted to the H+ / OH- form. The resin is color indicating and changes color from purple to clear upon exhaustion for an easy to see visual indication of resin condition when used in a transparent filter housing. 567g of resin fills one standard 10-inch refillable cartridge, packed tight for maximum efficiency. Color indicating resin changes from purple to clear upon resin exhaustion for visual monitoring of resin condition. Best after reverse osmosis for zero TDS for the aquatics industry. Recommend pre-filter with catalytic carbon/carbon block to extend resin if chloramines are present in source water. The Benefits Reduces TDS to zero as final stage after RO membrane Creates consistent, safe, ultra-pure water High capacity and performance laboratory grade resin For use in fresh and saltwater aquarium water supply systems, and RO filtration systems Indicating resin changes from purple to clear once exhausted About Kolar Labs Kolar Labs has set a new standard of success for improving water quality in aquatic environments for aquariums, ponds, and fisheries.

Best used after reverse osmosis for zero TDS ultra-pure water for the aquatics industry. Quality is Our Strength Kolar Labs mixed bed DI Deionization Resin blend is the perfect solution for aquarium systems and other applications where ultra-pure water is required. The nuclear grade, mixed bed resin is prepared from component anion and cation resins which have been manufactured with the highest degree of purity and converted to the H+ / OH- form. Use after your RO membrane to reduce total dissolved solids (TDS) to zero in your RODI system. We offer standard (non-indicating) and color-changing (indicating) formulations. The indicating resin changes from purple to clear once exhausted for a visual indication of resin condition. The non-color indicating retains its beige color through exhaustion, and saves you money if you already monitor TDS which is the most accurate approach for consistent ultra-pure water production. Use the ultrapure water from your RODI system after remineralization for your freshwater, brackish, saltwater, reef or marine aquarium or tank.
