For a 24\" × 24\" footprint, it delivers measurable PAR across every coral category, provided you understand what intensity your animals actually need and how to get them there safely.\u003c\/p\u003e\n\n\u003ch3\u003eCoral Compatibility \u0026amp; PAR Reference\u003c\/h3\u003e\n\u003cp\u003ePAR (Photosynthetically Active Radiation, measured in µmol photons\/m²\/s) is the scientific unit for light intensity at the coral surface.
