Nova Refugium Light by Reef Casa — 9W LED Macroalgae Spectrum 660/420/470 nm Fanless - Reef Casa

The Nova Refugium Light by Reef Casa is a 9-watt LED light specifically designed to stimulate macroalgae growth in reef tank refugiums. Its optimized light spectrum combines red (660 nm), violet (420 nm), and blue (470 nm) LEDs—the ideal wavelengths for photosynthesis in macroalgae such as chaetomorpha, caulerpa, and ornamental red algae. With its ultra-compact dimensions of 10 x 10 x 1.3 cm and silent fanless design, the Nova integrates perfectly into the rear filter chambers of Reef Casa aquariums.

Key Advantages

• Optimized spectrum for macroalgae: 660 nm (red), 420 nm (violet), and 470 nm (blue) LEDs—the exact blend to maximize photosynthesis and macroalgae growth in the refugium.
• Ultra-compact and slim: Only 10 x 10 x 1.3 cm—fits into the rear filter chamber of all-in-one Reef Casa aquariums without blocking access to filter media.
• Silent (fanless): Fanless design with passive heat sink. Zero noise.
• Dual mounting: 24 cm flexible gooseneck arm included, or direct mounting to the back of Reef Casa aquariums for a clean look without the gooseneck.
• Efficient 9W: Minimal power consumption with effective coverage of 25 x 15 cm—sufficient for small to medium-sized refugiums.

Installation and Use

The Nova offers two mounting options. Use the 24 cm gooseneck arm to position the light above the rear filter chamber containing your macroalgae. Alternatively, attach the Nova directly to the back of your Reef Casa aquarium for a discreet mount without a gooseneck. For an effective refugium, operate the Nova on a reverse cycle (on at night, off during the day) to stabilize the aquarium's pH overnight and maximize nutrient export by the macroalgae.

Compatibility

The Nova is designed to fit into the rear filter chambers of Reef Casa aquariums, particularly the Studio 12, Laguna 24, and La Casa 35. It is also compatible with any aquarium that has a refugium section or a sump requiring specialized lighting for macroalgae.

Frequently Asked Questions

Why use separate refugium lighting in a reef aquarium?

A refugium with macroalgae illuminated on a reverse cycle (night) absorbs excess nitrates and phosphates, stabilizes nighttime pH, and produces copepods that naturally feed your corals and fish. The Nova provides the exact spectrum needed to maximize the growth of these macroalgae.

Which macroalgae can be grown with the Nova Refugium Light?

The Nova's spectrum (660 nm red, 420 nm violet, 470 nm blue) is optimized for chaetomorpha, caulerpa, ornamental red macroalgae, and dragon's breath. Chaetomorpha is the most popular in refugiums because it is easy to maintain and very effective for nutrient export.

Can the Nova replace coral lighting such as the Beam or Halo?

No. The Nova's spectrum is designed specifically for macroalgae and not for photosynthetic corals. For corals, use the Reef Casa Beam (soft corals/LPS) or the Halo/Manta (all corals including SPS). The Nova is supplementary lighting intended only for the refugium.
