Spherical Phosphate-Adsorption Media for Use in All Freshwater & Marine Aquaria


  • Advanced adsorbent of phosphate and silicate; provides rapid results.
  • May be used on an on-going basis as part of a sensible nutrient-control program.
  • Spherical shape and porosity maximize reactive surface area; promotes reactivity and
    efficiency by maximizing contact time and minimizing tendency to pack and channel water,
    and outperforms competing non-spherical phosphate-adsorbent media.
  • Recommended usage is 2 g of Extrax Phos per 1 US-gallon (3.8 L) in aquarium; 600 grams
    will adsorb up to 20 mg/L phosphate in 300 US-gallons (1,136 L).
  • Does not release phosphate, silicate, or soluble compounds into aquarium system .
  • Safe for use in all freshwater and marine aquaria, including freshwater planted systems
    and reef systems.
