Brightwell Extrax Phos ~ 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.
