Acropora corals are one of the most beautiful and diverse groups of corals in a reef tank. They come in various shapes and colors, making them a favorite among reef enthusiasts and SPS lovers. However, these corals require special care and attention to thrive in a reef tank. In this blog, we will discuss how to care for Acropora in a reef tank.

Proper Water Parameters:

Acropora corals require stable and pristine water conditions to grow and thrive. The water parameters should be as follows:

  • Temperature: 76-82°F (24-28°C)
  • Salinity: 1.025-1.026
  • pH: 8.1-8.4
  • Alkalinity: 8-12 dKH
  • Calcium: 400-450 ppm
  • Magnesium: 1200-1350 ppm
  • Nitrate: <5 ppm
  • Phosphate: <0.03 ppm

It's essential to monitor these parameters regularly and make adjustments if necessary.


Acropora corals require high-intensity lighting to photosynthesize and grow. LED lights are the most commonly used lights in reef tanks as they provide a full spectrum of light that promotes coral growth. It's recommended to keep the lighting on for 8-10 hours per day.

Water Flow:

Acropora corals require high water flow to thrive. It helps to remove waste and debris and bring essential nutrients to the coral. It's recommended to have a water flow of 10-15 times the volume of the tank per hour.


Acropora corals are photosynthetic and obtain most of their nutrients from light. However, they do require additional feeding to grow and maintain their vibrant colors. You can target feed them with reef-roids or other coral foods, or you can add a plankton-based coral food to the water column.

Water Changes:

Regular water changes are crucial for the overall health of your reef tank, including your Acropora corals. It helps to remove excess nutrients and replenish trace elements necessary for coral growth. It's recommended to perform a 10-20% water change every two weeks.


Acropora corals require high water flow and intense lighting, so it's essential to place them in a location that receives both. They should be placed on rocks or other stable surfaces that provide adequate support.

Avoid Overcrowding:

Overcrowding can lead to aggressive competition between corals for space and nutrients. It's essential to provide enough space for each Acropora coral to thrive.

In conclusion, Acropora corals are stunning additions to any reef tank. However, they require special care and attention to thrive. By following the tips above, you can ensure that your Acropora corals are healthy, vibrant, and beautiful for years to come.
