Proven Ultrasonic Results Against Harmful Algae
Algae Control Australia’s Pulsar 4400 achieved up to 99.6% algae reduction in tests against red tide, golden algae, and Microcystis aeruginosa. Independent labs confirmed our ultrasonic technology as a safe, chemical-free solution for protecting waterways and aquaculture.

Case 1: Karenia brevis (Red Tide)
Results:
Initial Count: 4,579 cells/mL
After 4 Days of ultrasonic treatment: 20 cells/mL remained — a 99.6% reduction.
Significance: Demonstrated that ultrasound can halt red tide–like blooms in inland waterways and coastal channels.
Case 2: Prymnesium parvum (Golden Algae)
Results:
Initial Count: 47,000 cells/L
After 3 Days of ultrasonic treatment: No living golden algae cells detected.
Importance: Golden algae blooms trigger fish kills when counts exceed 10,000 cells/L. ACA’s treatment eliminated this risk entirely.
Additional Relevance: The same ultrasonic frequencies also proved effective against red tide algae in Florida laboratory tests.

Case 3: Microcystis aeruginosa (Blue-Green Algae)
Results:
Initial Count: 1,603 cells/mL
After 4 Days: reduced to just 23.6 cells/mL — a 98.5% reduction.
Verified by Dr. Paul Zimba at Rice Rivers Center (May 2023).
Lab imagery confirmed damage to the algae’s gas vesicles, photographed via transmission electron microscope.
