Algae are a natural part of aquatic ecosystems—but when they grow out of control, they can quickly damage the health, appearance, and value of a pond or lake. Excess nutrients like nitrogen and phosphorus can lead to harmful blooms, foul odors, pH fluctuations, and suspended solids that disrupt water quality.

Among the most problematic types are blue-green algae (cyanobacteria), which are known to produce toxins dangerous to pets, wildlife, and humans. Traditional solutions often rely on chemicals, which can solve one issue while creating others—like increasing nutrient release from the sediment or harming beneficial organisms.

The SonicPure Pulsar 4400 offers a sustainable alternative.

Understanding SonicPure’s Ultrasonic Approach

SonicPure systems use precisely tuned ultrasonic sound waves that travel through the entire water column. These waves target algae and biofilm at the cellular level, without affecting fish, zooplankton, or aquatic plants.

How It Works

  • The Pulsar 4400 emits over 4,000 discrete ultrasonic frequencies, covering the full range of algae species—from green algae to cyanobacteria.
  • Ultrasonic waves disrupt the algae cell’s structural resonance, affecting its internal mechanisms.
  • Gas within the cell escapes through the outer membrane.
  • Without buoyancy, the algae sink below the light zone, where they can’t photosynthesize.
  • The algae die off naturally, without chemical reactions or toxin spikes.

This process reduces cyanotoxins over time and avoids the problems associated with algicides.

Benefits of the Pulsar 4400 System

✔ Chemical-Free Algae Control

Eliminates the need for copper sulphate and other algicides that can harm aquatic ecosystems.

✔ Safe for Aquatic Life

Ultrasound leaves beneficial bacteria, fish, and plants untouched.

✔ Prevents Future Blooms

Unlike chemical treatments, ultrasound does not cause phosphorus release that triggers new cycles of algal growth.

✔ 24/7 Automated Operation

The Pulsar 4400 runs continuously, maintaining balanced and healthy water conditions.

✔ Rapid, Reliable Water Clarity

Hospitals, municipalities, farms, and private facilities use this technology for predictable, measurable results.

SonicPure’s Pulsar 4400 provides powerful, long-term algae and biofilm control—helping water stewards protect their environment and their community without compromise.
