Introduction: A Natural Solution for Delicate Shellfish
In shellfish holding systems such as our Lobster Pod and Crab Pod, maintaining stable water chemistry is critical — especially for sensitive species such as sea urchins. Even small fluctuations in pH levels can cause stress and impact survival. At Todd Fish Tech, we’ve developed an algal scrubber that harnesses the natural power of seaweed to maintain a steady, healthy aquatic environment.
How It Works: Seaweed as a Biofilter
The algal scrubber operates as a living filter. Inside the unit, seaweed grows under constant LED lighting and is kept in gentle motion by a spray bar system. As water from the main tank circulates through the scrubber, the seaweed absorbs nitrates — the end product of the ammonia, nitrite and nitrate cycle — along with carbon dioxide.
In return, the seaweed releases oxygen and helps stabilise the pH of the water. This natural process effectively “buffers” the system, reducing chemical fluctuations and creating an environment where delicate species can thrive.
Why It Matters: Stable pH and Reduced Nitrate Levels
For species like sea urchins, maintaining stable calcium and pH levels is essential for shell and spine formation. The algal scrubber’s natural regulation of these parameters supports long-term health, while the reduction in nitrates prevents water quality decline.
By keeping nitrate levels low and pH steady, the scrubber helps protect sensitive shellfish from stress, resulting in a more resilient holding environment.
Designed for Integration and Efficiency
This adaptable feature can be added to any Todd Fish Tech shellfish holding system, including the Crab Pod or Lobster Pod. Its efficient design also means it may reduce the need for frequent water changes, saving both time and resources.
Each unit is built with robust, shellfish safe materials and can be customised to suit specific requirements — making it an ideal addition for hatcheries, research aquaria and shellfish merchants working with delicate species.
Conclusion: Smarter, Greener Water Management
By integrating natural biological processes into advanced engineering, the Todd Fish Tech algal scrubber offers a sustainable solution for water quality management. It’s another example of how we combine science, innovation and practicality to support the shellfish and fishing industries worldwide.
