Next steps

  • ▸ Correct your PAR meter reading using the PAR underwater calculator — Apogee MQ-500 / MQ-200 in-air sensors under-read by ~25 %.
  • ▸ Convert peak PAR to DLI with the DLI calculator — that's the metric corals actually care about.
  • ▸ Reference the lighting guide for PAR targets by coral type.
