Practical Nutrient Management
for Healthier Fisheries

Proven phosphorus control to support aquatic biodiversity and water clarity

Nutrient Pollution Undermines Fishery Success


Whether you manage angling lakes, conservation waters, or commercial fisheries, nutrient overload—especially phosphorus—can quickly compromise aquatic health.


Uncontrolled nutrients lead to:

  • Harmful algal blooms (HABs)
  • Dense aquatic weed growth
  • Oxygen depletion and fish stress
  • Increased need for weed removal and aeration
  • Diminished angler experience



Phoslock provides a safe, effective solution that targets the cause—not just the symptoms.

Engineered to Work With Nature, Not Against It


Phoslock is made from modified natural bentonite clay. It binds excess phosphate in water and sediment, making it unavailable for algae and cyanobacteria.



Used across:

  • Fisheries and angling lakes
  • Conservation-grade water bodies
  • Sites of Special Scientific Interest (SSSIs)
  • Projects involving Natural England and the Environment Agency


Benefits:

  • Non-toxic to fish, invertebrates, and aquatic plants
  • Easy to apply with standard equipment
  • Long-lasting phosphorus control
  • Minimal disruption to fishery operations

Reduce Operational Costs and Improve Water Quality


Many traditional methods (dredging, aeration, weed cutting) are expensive and repetitive.


Phoslock complements or replaces these approaches by stabilising nutrient levels at the root.

  • Reduces algal pressure on oxygen levels
  • Improves clarity and aesthetics
  • Supports healthier fish stocks
  • Integrates easily with your existing maintenance plan
