Phoslock Phosphorus Locking Technology. 

Phoslock® gets to the root of many water bodies' persistently poor water quality—excessive phosphorus levels.

Improved Water Quality, One Application

Phoslock's Phosphorus Locking Technology allows for one early-season application that significantly reduce phosphorus levels, improving water quality.  Permanently locking phosphorus into an inert mineral that sinks to the pond bottom, Phoslock cuts off the food source for most recurring algal blooms. 

Excessive levels of phosphorus in water and sediments alter the balance of an aquatic ecosystem and degrade water quality.  Even when external sources of phosphorus have been curtailed, internal recycling of phosphorus in water bodies can continue to degrade water quality.  Phoslock resets that process, bringing ponds back from a eutrophic state and delivering lasting water quality improvement.

  • Significantly reduces phosphorus levels from the water column and underlying sediment, delivering long-term water quality restoration
  • Permanently removes phosphorus, starving algae of the freshwater limited, essential nutrient
