• 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
