CTO Acropora Divaricata- AK Rainbow Loom

AK Rainbow Loom: The Legendary Multi-Color Masterpiece

The AK Rainbow Loom isn’t just a coral- it’s a status symbol for SPS collectors. Originally made famous by top-tier reefers for its “woven” kaleidoscope of colors, this Acropora Divaricata remains one of the most searched-for and sought-after corals in the world.

The Color Spectrum:

• The Base: A neon, glowing yellow-green that provides an electric backdrop.

• The Tips: Intense, saturated “Barbie-Pink” growth tips that look hand-painted.

• The Highlights: As the colony matures, expect to see purple corallites and even hints of orange in the transition zones.

Why the AK Rainbow Loom is a Must-Have:

• • Proven Heritage: This is the legendary “Rainbow Loom” strain that everyone looks for, with the added stability of the ACROKINGDOM facility.

  • Fast Grower: Once established, this coral is known for its relatively rapid growth rate, allowing you to develop a stunning multi-colored colony in no time.

  • High-Contrast Display: No other coral provides this specific combination of primary colors, making it the perfect focal point for your upper rockwork.

• Cut to Order Fragments (CTO) typically measure around 1 to 1.5 inches. Please allow 1 to 2 weeks for healing before shipping!
• Acropora thrives under stable water parameters. If you want to learn more about how we grow this coral, including water chemistry, light, and flow, please check out our All About Our Systems page.

• Key Requirements for Healthy Acropora Divaricata- AK Rainbow Loom

  Water Flow – Acropora corals naturally thrive in reef zones with intense currents. Strong, varied water movement in an aquarium removes waste and delivers nutrients to coral.

  Water Quality – Maintaining low nitrate and phosphate levels is critical for Acropora’s health. Poor water quality can slow their growth and negatively impact their overall condition.

  Lighting – In a reef tank, corals positioned near the top will receive higher light exposure, while those below may be shaded. This can affect their development, so careful placement and lighting adjustments may be necessary.

  Water Chemistry – These corals depend on stable levels of Calcium, Alkalinity, and Magnesium to build their skeletal structures.

  Feeding – Regular feeding with DIY Fish Food: How to Make Fish Food and Save Money supports Acropora’s growth and enhances coloration. Additionally, the presence of fish in the tank contributes to their overall well-being by providing natural nutrients.

  The Importance of Flow for Vibrant Acropora Coloration

  Preventing Detritus and Enhancing Nutrient Uptake

  Strong, turbulent water flow is essential for Acropora corals, as it prevents detritus from settling on their surface and ensures optimal nutrient absorption. Without proper flow, debris can accumulate, leading to poor photosynthesis and dull coloration.

  Improving Gas Exchange and Coral Health

  High-energy water movement promotes oxygen exchange, removes metabolic waste, and enhances polyp extension, which contributes to deeper, more vibrant colors. Stagnant water can cause tissue recession, increased algae growth, and poor overall health, dulling the coral’s natural hues.

  Creating the Ideal Flow Patterns

  To achieve the best coloration, use wavemakers or gyre pumps to create randomized, multi-directional flow that mimics natural reef currents. Direct, linear flow is not enough—corals need a dynamic, ever-changing water movement to bring out their most vivid colors.
