Speed, Baby, Speed

Like all other products in our stable,  Agent Green phosphate remover is formulated for maximum performance and efficiency.

Phosphate removal is a game of speed.  To enjoy a true zero phosphate environment, one must remove phosphate faster than it can accumulate.  Where other phosphate removers fail in this endeavor is their lack of speed of removal.  Speed is what it takes to remove phosphate from the water column as well as absorbed phosphate.  Only Agent Green has the speed to remove phosphate faster than it can accumulate.

 So What Exactly Happens?

Agent Green initiates an ion exchange, which capitalizes on the attraction between calcium and phosphate to create insoluble beads. These “beads” are insoluble inert substances that are harmless to aquatic wildlife.  When introduced into a high flow area of the system, Agent Green will create a smokey effect in the water instantly.  The denser the smoke, the more removal that is taking place.  This smokiness is the evidence that phosphate is being precipitated out of the system.


  • Removes Phosphates Instantly
  • Bound Phosphates Remain Insoluble Until Removed By Filtration
  • Safe For Aquatic Wildlife Including Corals

Agent Green Is Safe

It is important to note there are various formulations of lanthanum chloride.  Some would not be practical for use with livestock.  Agent Green, however, carries no risks to freshwater nor marine life.  As in all other aspects of life, the right tool is required for the right job. Always Trust The Shark with  the safety of your livestock.


No other phosphate removal method offers the variable control as Agent Green.  Phosphate removal can be measured by the directed dose.  Performance of any other removal system is largely unpredictable.
