Green Millepora

(Acropora millepora)

• Lighting: High (200–400+ PAR); stable, intense lighting needed for vibrant color and healthy growth.

• Flow: High, turbulent; strong water movement keeps polyps extended and prevents detritus buildup.

• Water Parameters:

  • Temp: 76–80°F

  • Salinity: 1.025–1.026

  • Alkalinity: 8–10 dKH

  • Calcium: 420–450 ppm

  • Magnesium: 1250–1350 ppm

  • Nitrate: <5 ppm

  • Phosphate: <0.03 ppm

• Feeding: Primarily photosynthetic; can accept fine particulate foods (reef roids, coral plankton) to supplement growth.

• Placement: Upper rockwork; requires strong light and high flow. Frag plugs or stable rockwork recommended due to brittle skeleton.

• Aggression: Low; generally peaceful, does not sting neighbors, but needs space to grow outward.

• Difficulty: Advanced; sensitive to fluctuations in water chemistry, temperature, and lighting.
