The Light Reactor LR-150 / LR-200 - Reef Octopus is an advanced, self-contained solution designed to cultivate macroalgae within a controlled environment. By growing algae inside a dedicated chamber, you gain full command over the flow rate and nutrient export process while maintaining a clean and organized filtration system. Each unit comes equipped with a reliable Aquatrance feed pump to ensure consistent water movement through the reactor for optimal performance.

NATURAL FILTRATION

This innovative reactor functions as a natural filtration system, harnessing the power of macroalgae such as Chaetomorpha to actively absorb and remove algae-producing nutrients like nitrates and phosphates from your aquarium water. As the macroalgae grows, it continuously extracts these unwanted compounds. Periodic harvesting of the algae physically removes the bound nutrients from your system, effectively purifying the water and reducing the need for chemical media.

In addition to its filtration benefits, the reactor doubles as a protected refuge for beneficial microfauna. Tiny organisms such as copepods and amphipods can thrive and reproduce within the safe environment of the reactor, providing a steady and natural food source for your aquarium inhabitants.

MAXIMUM LIGHT EXPOSURE

At the heart of the reactor is a unique triangular waterproof LED light strip (IP67 certified) engineered to deliver 360-degree illumination inside the chamber. This close-proximity, high-output LED design ensures that every strand of macroalgae receives maximum light exposure, dramatically improving growth rates and nutrient uptake efficiency. The built-in heat sink and low-wattage design provide safe, energy-efficient operation while minimizing heat transfer to your aquarium.
