Compatibility math
Coverage and PAR
fixture coverage >= tank footprint and PAR >= coral target
Example: A common 75g footprint is 864 sq in; this fixture lists about 576 sq in and 280 PAR at 18 in.
ReefCrafter checks spread and intensity separately because a bright hotspot still leaves dim edges.
Risk notes
- The common mistake is buying a light that grows soft corals now but cannot support the mixed or SPS reef the keeper already wants.
- Large or SPS-heavy tanks may need multiple fixtures even when one light technically fits the gallons.
