  • Designed to be used in marine and hard freshwater aquariums with a pH of 7.5 or over
  • Utilizes NanoIntelex Technology to create an enhanced, “ultra-activated” material with the capacity to outperform conventional phosphate-adsorption media by over 1,000%
  • Removes ~30 – 100 mg phosphate per 1 g of media, dependant upon initial concentration in system.
  • Open structure and high surface area results in superior flow-through characteristics and adsorptive efficiency.
  • Higher adsorptive capacity relative to conventional media results in smaller space requirements to achieve equivalent phosphate uptake.
  • Capable of removing phosphate for over 1-year after initial placement in aquatic system.
  • May be used in conjunction with Xport Bio Cubes and Xport NO3 Cubes
