• Lighting: Moderate (75–125 PAR), avoid sudden intensity changes.

• Flow: Moderate, indirect; polyps should sway gently, not whip.

• Water Parameters:

  • Temp: 76–80°F

  • Salinity: 1.025–1.026

  • Alkalinity: 8–9.5 dKH

  • Calcium: 400–450 ppm

  • Magnesium: 1250–1350 ppm

  • Nitrate: 5–15 ppm

  • Phosphate: 0.03–0.1 ppm

• Feeding: Photosynthetic; benefits from occasional target feeding (mysis, brine, reef roids).
