SonicPure®
Saves Summer
As harmful algal blooms shut down lakes across the United States, SonicPure is launching a first-of-its-kind pilot initiative to help qualifying state and county waterbodies fight HABs using chemical-free ultrasonic treatment technology.
The Crisis:
Our Lakes Are Closing.
Warmer temperatures, agricultural nutrient loading, and prolonged drought have created a perfect storm. Harmful Algal Blooms (HABs) are accelerating in frequency, severity, and duration across the country.
- Public beaches shut down during peak recreation season
- Municipal drinking water supplies threatened by cyanotoxins
- Massive fish kills damaging local ecosystems
- Rising costs of chemical algaecides with diminishing returns
Meet the
Pulsar 4400
Our fourth-generation ultrasonic system — the technology powering every Saves Summer deployment. Engineered for full-spectrum coverage, designed for easy deployment, simple operation, and minimal maintenance.
360° Coverage
Targets algae and biofilm in every direction for complete water column control.
4,400 Frequencies
Tuned to combat common HAB-forming algae, including cyanobacteria and blue-green algae.
Solar Compatible
Low-power design perfect for off-grid reservoirs and solar-powered installations.
Safe for Fish & Plants
Harmless to aquatic life — preserves the healthy ecosystem you're protecting.
Physics, Not Chemistry.
SonicPure’s flagship Pulsar 4400 uses targeted ultrasonic frequencies to disrupt the cellular structures of harmful algae, cyanobacteria, and blue-green algae. It’s effective, continuous, and completely chemical-free.
Ultrasonic Disruption
Emits specific sound wave frequencies that cause algae to lose buoyancy, sink, and naturally die off.
Zero Chemicals
No copper sulfate, no algaecides. We add no compounds to the water column, preserving the aquatic ecosystem.
Continuous Mitigation
Operates 24/7 to both combat active blooms and prevent new blooms from forming.
One Complete System
Every Saves Summer deployment pairs ultrasonic treatment with cloud-based continuous system performance monitoring and optional water-quality tracking.
Pulsar 4400 Array
Four transducers. 360° coverage. 4,400 discrete frequencies across two bands, with up to a 400 m radial reach on cyanobacteria and blue-green algae.
SenseIQ Probes
Optional SenseIQ probes can track water quality before, during, and after treatment, including chlorophyll-a, phycocyanin, pH, dissolved oxygen, turbidity, and more, with data logged automatically.
IQCloud Platform
Real-time system status, water-quality dashboards with historical trending, and instant alerts on power, connectivity, or threshold breaches — accessible from any device, with regulatory reporting export.
Results in 7–10 Days
Measurable reduction in algae and visible clarity improvement within 7–10 days for cyanobacteria under continuous operation. Other species operate on different timelines — we'll tell you exactly what to expect for yours.
-
Day 1–3
Gas vesicle disruption begins
Cells in the direct acoustic field begin losing buoyancy. IQCloud logs chlorophyll-a and phycocyanin baseline from day one.
-
Day 7–10 — Cyanobacteria
Visible impact: surface blooms
Blue-green algae surface accumulations diminish. Water clarity measurably improves. Chlorophyll-a reduction detectable. Odor events cease.
-
Week 3–4 — Green Algae & Diatoms
Cellular disruption takes effect
Green algae and diatoms, which lack gas vesicles, are disrupted via cell membrane stress and oxidative processes.
-
Ongoing — Biofilm
Prevention begins immediately
Simulated turbulence prevents new anaerobic bacterial attachment from day one. Existing biofilm degrades over 2–4 weeks.
The 7–10 day figure is specific to cyanobacteria (blue-green algae). It reflects the biology of gas vesicle disruption and the time required for a sufficient portion of the population to lose buoyancy, sink, and die in the absence of photosynthesis.
For sites with heavier nutrient loads or multiple algae species, expect a more complex trajectory. We set those expectations during site assessment, not after deployment.
What Drives The Timeline And What Can Slow It
Treatment pace depends on water temperature, nutrient (nitrogen and phosphorus) loading, depth and stratification, the dominant algae species, and how continuously the array operates. Warmer, well-mixed water dominated by a single cyanobacteria species responds fastest.
Heavy external nutrient inflow, frequent re-seeding from upstream sources, or dense established biofilm can extend the trajectory. We model these factors during site assessment so your expected timeline reflects your specific waterbody.

Apply For The Pilot
Don't let another summer be lost to toxic blooms. Submit your waterbody for consideration in the SonicPure Saves Summer initiative.
Pilot availability is limited. Applications will be reviewed and selected at SonicPure’s discretion based on program criteria, including waterbody conditions, HAB history, site access, deployment feasibility, monitoring needs, and suitability for ultrasonic treatment. Submission of an application does not guarantee selection, equipment availability, or deployment.
Application Received
Thank you for applying to the SonicPure Saves Summer program. Our team will review your submission and reach out within 5 business days.
