Next steps

  • Correct your PAR meter reading using the PAR underwater calculator — uncorrected, the Apogee MQ-500 reads about 24 % low underwater (×1.32) and the older MQ-200 about 7 % low (×1.08); the MQ-510 corrects itself.
  • 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.
