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 promoting reactivity and efficiency by maximizing contact time and minimizing tendency to pack and channel water.
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.
May be used with MicroBacter 7 as part of a low-nutrient approach to aquarium husbandry.
