Purpose-built for tanks demanding precise spectrum control over wide coverage areas, it's the fixture serious SPS keepers scale to when a single Hydra 32HD no longer gets PAR where it needs to be.\u003c\/p\u003e\n\n\u003ch3\u003eCoral Compatibility \u0026amp; PAR Reference\u003c\/h3\u003e\n\u003cp\u003ePAR (Photosynthetically Active Radiation, µmol photons\/m²\/s) is the scientifically measurable unit of light usable by coral zooxanthellae (\u003cem\u003eSymbiodinium\u003c\/em\u003e spp.) for photosynthesis. Higher LED count on the 64HD produces more even PAR distribution with fewer \"hot spots\" directly below the fixture — the critical advantage for larger tanks and SPS colonies spread across the sand bed and rockwork.\u003c\/p\u003e\n\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:0.875rem;margin:14px 0;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background:rgba(59,130,246,0.08);text-align:left;\"\u003e\n\u003cth style=\"padding:10px 12px;border-bottom:2px solid rgba(128,128,128,0.15);\"\u003eCoral Type\u003c\/th\u003e\n\u003cth style=\"padding:10px 12px;border-bottom:2px solid rgba(128,128,128,0.15);\"\u003eTarget PAR (µmol\/m²\/s)\u003c\/th\u003e\n\u003cth style=\"padding:10px 12px;border-bottom:2px solid rgba(128,128,128,0.15);\"\u003eHydra 64HD Intensity\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003eSoft corals (mushrooms, zoanthids, leathers)\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e25–75\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e20–40%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:rgba(128,128,128,0.03);\"\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003eLPS (hammer, torch, frogspawn, brain corals)\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e50–200\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e30–60%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003eMixed reef (LPS + moderate SPS)\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e100–300\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;border-bottom:1px solid rgba(128,128,128,0.1);\"\u003e50–75%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:rgba(128,128,128,0.03);\"\u003e\n\u003ctd style=\"padding:9px 12px;\"\u003eSPS-dominant (acropora, montipora, stylophora)\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;\"\u003e200–500\u003c\/td\u003e\n\u003ctd style=\"padding:9px 12px;\"\u003e70–100% + Hyperdrive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"font-size:0.8rem;opacity:0.65;font-style:italic;\"\u003ePAR measured at 8–10\" below fixture in open water at peak output.
