RR The Vinh Acropora

RR The Vinh Acropora is a legendary high-end SPS coral. It shows intense green branches with bright blue tips and polyps. With the right care, it becomes a stunning centerpiece in any modern reef tank.

RR The Vinh Basics and Ideal Tank Conditions

RR The Vinh is a fast-growing Acropora. It prefers strong light and high, stable flow. This coral does best in mature, stable reef systems. Avoid adding it to new tanks under six months old.

Target strong lighting in the 250–400 PAR range. Many hobbyists keep it around 300 PAR for best color. Use high-quality LEDs or a T5/LED hybrid. Place frags in the upper third of the tank. Start lower and move up slowly over two to three weeks.

Flow should be strong and random. Aim for 30–50 times tank turnover per hour. Use two or more wavemakers on alternating modes. Avoid direct, constant blast on the tissue. You want the polyps to sway, not fold over.

Keep parameters very stable. Good targets include:

• Alkalinity: 8.0–8.6 dKH, daily swing under 0.3 dKH
• Calcium: 420–450 ppm
• Magnesium: 1300–1400 ppm
• Nitrate: 5–15 ppm
• Phosphate: 0.03–0.08 ppm

RR The Vinh hates big swings. Test alkalinity at least three times per week. Use a dosing pump or calcium reactor for consistency.

Placement, Feeding, and Troubleshooting Color

Place new RR The Vinh frags on a removable rack first. Give them 150–200 PAR for the first week. Then increase light by 10–15% each week until you reach your target. Watch for pale tissue or burnt tips. If this happens, reduce light intensity by 20% and increase feeding.

Though it is photosynthetic, RR The Vinh benefits from extra nutrition. Feed the tank 2–3 times per week with fine coral foods. Turn off return pumps for 15–20 minutes. Leave powerheads on low to keep food suspended. This supports growth and deeper coloration.

• Broadcast feed powdered coral food at night.
• Target feed lightly with a turkey baster, avoiding direct blasts.
• Maintain a small but measurable nitrate and phosphate level.

Common problems include browned-out color, slow growth, and tip burn. Brown color often means low light or excess nutrients. Increase PAR slightly and improve export with a skimmer or refugium. Pale or bleached tissue usually means too much light or too clean water.

• If tips burn, check alkalinity for sudden jumps.
• If tissue recedes from the base, inspect for pests like AEFW or red bugs.
• Dip new frags for 5–10 minutes in a coral dip before adding.

With stable parameters, careful acclimation, and consistent feeding, RR The Vinh will reward you. Expect thick, branching growth and intense color within a few months. It can quickly become the highlight of your SPS collection.
