Frag tank lighting is about repeatability
In a display reef, you can “hide” mistakes with aquascape and shaded zones. In a frag tank, lighting is direct and uniform—so consistency matters even more.
What to dial in first
- Photoperiod: keep it consistent
- Intensity: acclimate frags slowly
- Spectrum: choose a stable profile and avoid constant tweaking
Acclimation rule
New frags often bleach from sudden light increases. Start lower and ramp up slowly over days/weeks.
Pair lighting with flow
Higher light usually demands better flow and stable alkalinity to support growth.
Support products
Stability products can help after changes, water swaps, and parameter corrections.
