The Valhalla Acropora, also known as the Acropora sp., is a type of SPS (Small Polyp Stony) coral that can be quite challenging to care for. This coral is prized for its stunning and vibrant colors but requires specific conditions to thrive in a reef aquarium. Here are some care guidelines for the Valhalla Acropora.


Valhalla Acropora requires very high-intensity lighting. Metal halide, T5, or high-quality LED lighting systems with a spectrum that includes blue and white light are typically recommended. Ensure that the lighting provides a high PAR (Photosynthetically Active Radiation) level, usually in the range of 300 to 450 PAR or even higher depending on the depth of your tank.

Water Parameters:

  • Maintain stable and pristine water quality with minimal fluctuations in temperature, salinity, and water chemistry.
  • Temperature: Keep it between 74°F to 80°F (23°C to 27°C).
  • Salinity: Maintain a specific gravity of 1.024-1.026.
  • pH: Maintain a pH level between 8.1 and 8.4.
  • Alkalinity: Keep alkalinity (KH) levels within the range of 7-10 dKH.
  • Calcium and Magnesium: Maintain calcium levels around 380-450 ppm and magnesium levels around 1250-1350 ppm.

Water Flow:

Valhalla Acropora prefers strong and turbulent water flow. Ensure that the coral receives enough water movement to prevent detritus buildup and to supply nutrients.


These corals are primarily photosynthetic, deriving most of their energy from light. However, they can benefit from supplemental feeding with planktonic or micro-particulate foods occasionally. You can target-feed them with a specialized coral food, such as phytoplankton or zooplankton, once a week or less.

Water Quality Maintenance:

Regular water changes are essential to replenish trace elements and remove excess nutrients. Aim for weekly or bi-weekly water changes of 10-15% of the total water volume.


Place the Valhalla Acropora in the upper to middle section of the tank, as it prefers intense lighting. Ensure it has enough space to grow without coming into contact with other corals, as they can sting or overgrow them.


When introducing a Valhalla Acropora to your tank, acclimate it carefully to your tank's lighting and water conditions to prevent shock.

Disease and Pests:

Regularly inspect your corals for signs of diseases or pests like flatworms, nudibranchs, and Acropora-eating flatworms. Quarantine new corals and inspect existing ones to catch issues early.


If your Valhalla Acropora becomes too large or needs pruning, you can frag it carefully. Use proper tools and techniques to ensure the health of both the parent colony and the frag.


SPS corals, including the Valhalla Acropora, can be slow to adapt and grow. Be patient and consistent in your care to see the best results. Success with Valhalla Acropora care requires a deep understanding of the specific needs of the species and maintaining stability in water parameters. Regular monitoring and adjustments are essential to ensure the health and growth of this beautiful coral in your reef tank.
