Advanced Algae Reactor for Growing Macro-Algae - Use to reduce nitrates and phosphates in aquarium- Double sided Aquaray lighting board included- Compact design- Use internally or externally- Advanced, compact reactors specifically designed to grow macro-algae- This macro-algae can be used to reduce unwanted nutrients such as nitrate andphosphate from your reef aquarium and also help improve water quality Includes a high performance, double-sided LED board using AquaRay technologyand Samsung LEDs, with high PUR* and low power (9W) Versatile compact design allows the reactor to be installed internally in a sump oraquarium or externally as a stand-alone reactor Easily accessible for simple harvesting of algae, simply unscrew and pull the lid upIncludes pipework and fittings Designed for marine aquaria *PUR (photosynthetically usable radiation) will vary based on species of algae kept, however spectrum peaks are designed to mimic the photosynthetic needs of most algaes. The light incorporates a custom-engineered light spectrum developed alongside BioLumen Lighting to offer the most efficient photosynthetic processes to promote optimum algae growth inside the reactor.
