Pro Tips
- *Match your light schedule to the tank type - FOWLR tanks often do well with 8-10 hours of display lighting, while coral systems commonly run 9-12 hours with ramp periods.
- *Prioritize stable PAR over constantly changing spectrum, because corals respond better to consistency than frequent schedule tweaks.
- *Use gradual sunrise and sunset ramping when possible to reduce fish stress and avoid abrupt on-off lighting changes.
- *Check actual PAR at the sand bed and top rockwork before finalizing a schedule, especially if you keep SPS, LPS, or light-sensitive fish species.
- *Consider coverage and mounting height along with app features, because the best scheduler cannot fix poor spread or major shadowing.
