Lighting Coverage Visualizer

Pick your fixture and tank dimensions. We map estimated PAR coverage and highlight dim spots where SPS won’t thrive.

PAR targets by coral type

  • Soft corals: 60–120 PAR (low light tolerant)
  • LPS: 100–200 PAR (moderate, indirect)
  • Mixed reef: 150–250 PAR average
  • SPS dominant: 250–400+ PAR at top of rockwork

Validate before stocking: Software estimates assume ideal conditions. Use a real PAR meter (Apogee MQ-510 or Seneye) before placing light-demanding SPS. New corals must be acclimated by starting in shade and raising weekly.
