Codium Macroalgae

Regular price $24.99


Codium Macroalgae (Codium sp.)

Codium is a highly sought-after ornamental macroalgae that brings both elegance and function to reef aquariums. Known for its thick, velvety, dark green branches, Codium grows in a sculptural, tree-like form that adds depth, structure, and a natural aesthetic to any marine display.

Its sturdy growth habit makes it a hardy and low-maintenance choice for aquarists, while its branching fronds provide valuable habitat for pods, snails, and small invertebrates. In addition to its beauty, Codium helps with nutrient export, absorbing excess nitrates and phosphates to support a healthier, more balanced reef system.

Key benefits include:

  • Distinctive deep green, velvet-textured branches for aquascaping.
  • Provides microhabitat and grazing surfaces for beneficial critters.
  • Slower-growing and easy to manage compared to faster-spreading macroalgae.
  • Suitable for both display tanks and refugiums.

With its unique appearance and functional role, Codium Macroalgae is an excellent addition for reef keepers looking to enhance biodiversity while elevating the natural look of their 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.
