New 2 pack 2.5" x 10"  Nuclear Grade Mixed Bed Ion Exchange refillable cartridge filter containing , with indicator dye (Green), for water deionization and TDS reduction. This resin meets the stringent requirements of the Nuclear industry. Incorporated as a post Reverse Osmosis filter, 99.9% pure water is achievable. We use the filters on our reverse osmosis systems and found the water quality, after filtration, to approach 16 MOhm-cm, among the highest water purity achievable without distillation. Nuclear Grade resins are well suited for the water quality requirements of saltwater and reef aquarium enthusiasts, or anyone desiring highly pure water.
