Rr The Vinh Acropora: Color, Placement, and Care

Rr The Vinh Acropora is a standout SPS coral known for its intense yellow-to-golden base with contrasting red and sometimes green highlights. It’s stunning, but it demands stable, high-quality reef conditions. Here’s how to keep it thriving instead of browning out or receding.

Lighting and Placement

This Acropora prefers strong, stable light but can burn if you rush it.

• PAR target: 275–375 PAR once fully acclimated.
• Start low: Begin at the lower half of the rockwork and gradually move it up over 3–4 weeks.
• Light acclimation: Use your LED’s acclimation mode or reduce intensity by 20–30% for the first week.
• Color check: If it turns pale, lower intensity; if it browns, slowly increase PAR.

Flow, Stability, and Feeding

Like most high-end Acropora, Rr The Vinh rewards consistency more than anything else.

• Flow: Strong, random flow that keeps polyps moving but not blasting off tissue. Aim for alternating gyre or pulsing modes.
• Parameters: Keep these tight and stable:
  • Alkalinity: 8.0–9.0 dKH (swing < 0.3 dKH per day)
  • Calcium: 420–450 ppm
  • Magnesium: 1300–1400 ppm
  • Nitrate: 5–15 ppm; Phosphate: 0.03–0.08 ppm
• Feeding: Moderate nutrients plus occasional coral foods (amino acids or fine particulate foods 1–2× per week) help maintain color and growth.
• Mounting tip: Glue the frag to a clean, stable plug or rock shelf with room to table out; avoid shaded overhangs.

Quick check: If polyp extension is good and color is stable for 4+ weeks, you’ve likely nailed the light–flow–nutrient balance.

With patience, careful acclimation, and rock-solid stability, Rr The Vinh Acropora can become a bright centerpiece that instantly draws the eye in any SPS-dominated reef.
