Protecting Iconic Coastlines: The Eco-Friendly Algaecide Solution for Sydney’s Ocean Pools

April 05, 2026

Sydney’s Northern Beaches are home to some of Australia’s most heavily visited and iconic ocean swimming pools. From Palm Beach to Manly, these ocean-fed facilities are a staple of coastal life, but they face a constant natural enemy: the rapid build-up of moss, algae, and marine contaminants.

For the Northern Beaches Council, maintaining these pools isn’t just about aesthetics; it’s about public safety and environmental stewardship.

The Challenge: Why Traditional Chemicals Fail

Because these pools operate in a natural ocean-water environment, traditional treatments like chlorine are not a viable option. The council required an effective algaecide solution that could:

  • Control Algae Growth: Prevent hazardous, slippery surfaces that lead to slip and fall injuries.
  • Preserve Ecosystems: Ensure the treatment is safe for the surrounding marine life.
  • Maintain Water Quality: Prevent periodic closures that impact tens of thousands of swimmers annually.

The Solution: Chemron’s Algae Died B

To meet these “non-negotiable” requirements, the council implemented Algae Died B. This environmentally responsible formulation allows operators to limit algae growth without harming the broader marine environment.

Results & Outcomes

Since adopting this solution in 2019, the Northern Beaches Council has achieved remarkable results:

  • Year-Round Excellence: 12/12 months of consistent pool maintenance achieved.
  • Improved Safety: Significant reduction in slip hazards on pool surfaces and boat ramps.
  • National Reach: The success of this deployment has driven adoption by coastal councils across Australia.

“Algae Died B has been instrumental in keeping our ocean swimming pools pristine all year round… We also use it on boat ramps to remove slippery moss and algae so vehicles get good traction.”Operations Team, Northern Beaches Council

Beyond the Pool: Versatile Coastal Infrastructure

The effectiveness of this algaecide solution extends to boat ramps, where it restores surface traction for vehicles launching and retrieving boats. By removing slippery organic growth, the council has improved community safety across all coastal infrastructure.
