The AquaFX Add-On Chloramine Blaster Kit 10x2 is an essential upgrade for any saltwater RO/DI system, specifically designed to combat chloramines increasingly found in municipal water supplies. While standard carbon blocks effectively remove chlorine, they often leave behind toxic ammonia when chloramines are present. This innovative kit ensures comprehensive removal of both chlorine and ammonia, protecting your delicate reef inhabitants and the longevity of your RO membrane and DI resin. This kit features two high-grade catalytic carbon cartridges, engineered to be used in series for optimal contact time and maximum chloramine removal efficiency. Each cartridge is refillable, offering long-term cost savings and environmental benefits. The complete upgrade package includes one add-on canister and all necessary RO tubing for seamless integration into your existing RO/DI unit, ensuring a straightforward installation process. This add-on kit is ideal for reef aquarists living in areas where municipalities use chloramines in their water treatment. By effectively eliminating ammonia, it safeguards not only the health of your sensitive corals and fish but also extends the life of your RO membrane and DI resin, preventing premature exhaustion and costly replacements. It is a vital investment for maintaining pristine water quality and the overall stability of your saltwater aquarium environment.
