• 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 when exhausted.

• Safe for use in all freshwater and marine aquaria, including freshwater planted systems and reef systems.

• Solid
• 600-g
