Tabling Red Macroalgae

Regular price $49.99


Tabling Red Macroalgae (Rhodophyllis divaricata)

Bring true collector-grade macroalgae into your reef with Rhodophyllis divaricata, a stunning rare tabling red macroalgae prized for its unique growth form. Unlike most ornamental reds that grow as flowing fronds, this species develops flat, branching plates that expand outward and layer over one another—often compared to the look of a tabling Montipora, but with an intense crimson-red color that stands out under reef lighting.

Its compact, structured branches create a dramatic, architectural centerpiece for display tanks. Under blue and actinic lighting, the red plates deepen into a rich, saturated glow, adding bold contrast to corals and rockwork while staying neat and controlled in form.

More than just beautiful, Rhodophyllis can also support nutrient management in your system:

  • Helps consume nitrates and phosphates as it grows, supporting cleaner water.
  • Provides surface area and shelter for pods and microfauna, boosting biodiversity.
  • Typically grows in a stable, decorative shape rather than spreading aggressively.

This macro does best with moderate to strong lighting, good water movement, and stable reef parameters. Like many premium ornamental macros, it appreciates consistent nutrients and trace elements rather than ultra-stripped systems.

If you’re looking for a macroalgae that looks more like a sculptural reef organism than “plant life,” Rhodophyllis divaricata is one of the most distinctive and high-end choices you can add to a reef aquarium.

How We Farm Our Macroalgae

How We Farm Our Macroalgae

At New Dawn Aquaculture, all of our macroalgae are grown in fishless hydroponic flood tables. This lets us precisely control nutrition, maintain stability, and produce exceptionally clean, pest‑free macroalgae for your aquarium.

The Fertilizer System We Use

Macro Boost Nitrify Ammplify

Macroalgae require far more than just light to grow—they need a balanced supply of nutrients and trace elements. In a typical reef tank with fish, these nutrients are naturally supplied through feeding and fish waste. But because our systems contain no fish, we add those nutrients ourselves using a three‑part fertilizer system:

  • Macro Boost – A comprehensive trace‑element blend designed specifically for macroalgae health, pigmentation, and growth.
  • Ammplify – A reef‑safe nitrogen source used when no fish are present to supply the macroalgae with needed nitrogen.
  • Phosphorize – A clean, controlled phosphate source to support steady growth.

Together, these create a complete macroalgae fertilizer program: trace elements + nitrogen + phosphorus.

Do You Need All Three Products?

For most hobbyists, no — only the trace‑element component is typically required. In a stocked aquarium, your fish naturally provide nitrogen and phosphorus. So in most cases, all you need to replicate our results at home is:

Macro Boost (Trace Elements)

If you run a fishless refugium, a sterile macro system, or experience chronic nutrient deficiency ("zeroed‑out" nitrate/phosphate), then adding Ammplify and Phosphorize can help restore balanced growth.

Why This Matters

Healthy macroalgae need both major nutrients and trace elements. Our system ensures strong coloration, fast growth, and robust nutrient export — and that same foundation can help your macroalgae thrive at home.

Farmed, Tested, Trusted

Aquacultured coral, real farm standards, and products we actually use.

New Dawn is built around aquacultured coral, captive-bred marine life, and practical reef support from a real coral farm. Alongside the livestock we grow, we also offer reef products and essentials that reflect the systems, standards, and day-to-day practices behind the farm itself.

Aquacultured Coral

Aquacultured coral is grown in aquarium conditions, which helps it arrive better adapted to life in a reef tank. That often means hardier coral, more predictable performance, and a clearer connection between how it was grown and how it can thrive in a customer’s system.
