Seafuser
The Multivitamin for Marine Life
Protecting corals from heat stress and increasing growth rates through targeted marine nutrition.
Our mission
84% of the world’s coral reefs have already faced bleaching-level heat stress.*
Solutions today are not scalable or cost-efficient enough to match the speed of reef decline.

Nutrition for marine ecosystems
Marine organisms are often limited by a particular nutrient, slowing their growth and making them susceptible to stress.
Our solution
The Seafuser releases a low constant supply of nutrients (such as ammonium) over a small area, increasing the health and growth rate of marine life, such as corals, mangroves, seagrasses, and seaweeds.
The Seafusers can be positioned beside target organisms or spaced regularly to cover a greater area.
*Note: Prototype is still a work in progress. This image is for illustration purposes only.
How it works
Four simple steps.
-
The device is easily attached onto artificial reefs or fixed to the substrate.
-
The seafusers release a low, constant supply of nutrients raising the concentration over several months.
-
Corals and their algal partners take up the nutrients from the seawater, increasing their growth rates and resilience to heat stress.
-
Depending on the device, they biodegrade naturally or can be recycled.

Meet the founder
Oscar has been in the marine conservation sector for over 10 years with experience across Honduras, Malaysia, Fiji, Australia, and the Philippines, and has completed over 700 coral reef research dives.
He recently completed his PhD with Victoria University of Wellington where he studied the role of nitrogen in coral health and bleaching. His research indicated that the algae within the coral can become nitrogen limited as temperatures increase, potentially leading to bleaching.
Based on this, he developed Seafuser to give corals the nutrients they need to overcome the challenges of climate change.
