The Aquatic Life Twist-In Color Changing Dual Deionization Filter system is a very compact dual cartridge solution that efficiently combines color changing DI resin performance with our quick and easy to change twist-in replacement filter cartridges. After the water is filtered by a membrane (not included), there is usually a small amount of Total Dissolved Solids (TDS) left in the water. For aquariums it is important to remove the remaining TDS from the water. This is accomplished by filtering the water through a resin that is charged with Cation and Anion resins (H+ and OH-). As the resin absorbs the TDS, it will change color. When the entire resin has changed color, it is time to replace the DI filter. The new twist-in media cartridge design makes filter changes simple, easy and clean – no tools required and no mess! The twist-in cartridges can be easily changed in only seconds with just a quarter turn and without contact with used filter material. It is important the cartridges are installed post membrane filter to prolong the life of the Deionization (DI) cartridge. Assembled product dimensions: 6â€_x009d_L x 4â€_x009d_D x 13â€_x009d_H. Weight: 4lbs.
STAGE 4 – TWIST-IN MIXED BED COLOR CHANGING RESIN DEIONIZATION CARTRIDGE: Replace filter when resin changes color completely to amber. After the water is filtered by the membrane, there is usually a small amount of Total Dissolved Solids (TDS) left in the water. In certain non-drinking water applications, it is important to remove the remaining TDS from the water. This is accomplished by filtering the water through a resin that is charged with Cation and Anion resins (H+ and OH-). As the resin absorbs the TDS, it will change color. When all resin has changed color, it is time to replace the DI filter. Because the process of filtering the high quality water takes time, it is common to use a storage tank to collect filtered water, making it available on demand. Replacement Cartridge Item AL330380.
