The Reef Octopus Light Reactor is a natural filtration system designed to remove algae-producing nutrients from saltwater aquariums by utilizing macroalgae like Chaetomorpha for nutrient absorption. This innovative reactor features an IP67 certified triangular LED light strip that maximizes light exposure with 360-degree coverage, ensuring optimal growth of the macroalgae and efficient nutrient consumption. The system also includes integrated algae containment plates and can be installed either externally or in-sump, providing a safe haven for copepods and amphipods to reproduce naturally.
