    Algae Control Australia’s Aquaculture solution harnesses ultrasonic Pulsar technology and probiotic culture blocks (PBE-AP+CB) to safely suppress toxic algae—like cyanobacteria—while enhancing water quality and supporting healthy aquaculture ecosystems.

Ultrasonic Cyanobacteria Control & PBW for Ogranic Waste Cleanup

Toxic algal blooms, those vibrant yet deadly explosions of microorganisms, pose a significant threat to aquatic ecosystems and the burgeoning aquaculture industry.
These blooms can decimate fish populations, contaminate shellfish, and disrupt entire ecosystems, resulting in substantial economic losses and environmental damage. However, a promising solution is emerging from the depths of technological innovation with the use of Pulsar technology proving to decimate cyanobacteria population, while being safe for fish and making way for other dominant and beneficial species. 

Sonic Bloom: Ultrasound Technology Tackles Toxic Algae, Boosting Aquaculture.

 This technology utilizes 4400+ accurately targeted high-frequency sound waves to disrupt the cellular integrity of algae, effectively killing them without resorting to harsh chemicals. Here's how it works and its potential to revolutionize aquaculture:

Selective Targeting

  • With 4400+ pinpoint accurate frequencies being repeated continuously the Pulsar family is a must when it comes to both treatment and future defence against all unwanted species, safeguarding you from species you may not have experienced yet.

Reduced Mortality

By eliminating toxic algae, ultrasound technology significantly reduces fish and shellfish mortality rates, leading to increased yields and profitability for aquaculture farmers.

Improved Water Quality

Ultrasound treatment reduces the production of toxins and organic matter associated with algal blooms, resulting in cleaner and healthier water for aquatic organisms.   

Reduced Chemical Usage

Traditional treatments often involve the use of copper sulfate or other chemicals, which can have detrimental effects on the environment, Ultrasound offers a cost effective and environmentally friendly alternative.

The importance of oxygen in PBE BLOCK PLACEMENT

AP+CB Block delivering the same probiotic without the water clarity. Our continual studies in aquaculture are showing a pattern where the same beneficial bacterial species which are capable of living in aerobic or anaerobic environments, delivering two completely different outcomes in these areas for your crop health. The other area of interest is the importance of not clearing the water in aquaculture ponds.

Bacillus species thrive in aerobic environments, producing enzymes that boost gut health in fish and crustaceans. The results are clear: stronger survival rates, faster growth, and reduced bacterial disease in aquatic crops.

In contrast, anaerobic conditions reduce enzyme activity, leading to poor feed uptake, weak gut health, and low yields. Farmers often see uneven crop sizes at harvest and an increase in runts, with no reduction in disease pressure.

With PBE (Prebiotic Bacteria Enhancer) sinking blocks, shallow ponds under 3 feet deep have consistently delivered outstanding results thanks to their aerobic balance. However, deeper ponds (over 3 feet) often slip into anaerobic states, reducing effectiveness. To solve this, we developed PBE – AP+CB (Aquaculture Probiotic Culture Block).

This innovation comes in two forms:

  • Sinking blocks for shallow ponds.

  • Floating bent blocks for deeper ponds.

The floating design uses sunlight on its curved surface to enhance aerobic conditions, stimulating Bacillus to produce more beneficial enzymes without over-clarifying the water.

Trials in ponds 8–10 feet deep have shown the same exceptional results once only possible in shallow water — improved survival, healthier stock, and stronger yields.
