AI Prime Fuge 16HD Black 46W — LED Refugium Macroalgae - AquaIllumination

The AI Prime Fuge 16HD is the go-to LED light for reef aquarium refugiums. With a Photo Red and Red dominant spectrum specifically calibrated for macroalgae photosynthesis, this 46-watt fixture grows chaetomorpha and other macroalgae at an exceptional rate for natural nitrate and phosphate reduction. With a peak PAR of 160 µmol at 18 inches depth and a 24 x 24 in. coverage area, the Prime Fuge is powerful enough to cover most refugium compartments in reef sumps.

Why a Dedicated Refugium Spectrum?

Macroalgae like chaetomorpha need a completely different light spectrum than corals. Red wavelengths (Photo Red and Red) are the most efficient for algae photosynthesis, while Cool White and UV LEDs round out the spectrum for maximum balanced growth. The result: denser, healthier algae that absorbs more nitrates and phosphates from your water.

Key Technologies

• Optimized Photo Red Spectrum: Red-dominant spectrum specifically designed to maximize macroalgae photosynthesis — not a repurposed reef light
• HyperDrive: Dynamically adjusts power between LED channels for spectrum customization based on your needs
• TIR 80° Lenses: Custom-designed optics with over 90% efficiency and a diffuse exit surface for optimal color blending
• Dedicated Moonlight Channel: Allows simulating a day/night cycle in the refugium if desired

Mounting Options — Sold Separately

The Prime Fuge uses the same mounting accessories as the Prime 16HD lineup:

• Prime Tank Mount: Brushed aluminum mount for attaching directly to the sump rim
• Prime Flex Arm 12 in.: Flexible arm for positioning above the refugium compartment
• Prime Flex Arm 18 in.: Longer flexible arm for deeper sumps
• Prime Hanging Kit: Suspension kit if the sump is inside a closed cabinet

Usage Tips

The Prime Fuge is powerful enough to grow chaetomorpha too quickly in some cases. If this happens, reduce intensity or photoperiod through the Mobius app. For optimal nutrient reduction, run the refugium on a reverse cycle (light on when the display lighting is off) to stabilize nighttime pH.

Why Buy From ReefSolution

All AI Prime mounting accessories are available at ReefSolution. Complete your setup with the Prime Tank Mount or Prime Flex Arm 12 in. to mount the Fuge above your sump. Shipping available across Canada.

Frequently Asked Questions

Can the AI Prime Fuge grow chaetomorpha?

Yes. The Prime Fuge is specifically designed for macroalgae growth including chaetomorpha. Its Photo Red dominant spectrum maximizes photosynthesis and growth, naturally reducing nitrates and phosphates. With 160 µmol of PAR at 18 inches, it is powerful enough to cover most refugium compartments.

What is the difference between the Prime Fuge and the Prime 16HD Reef?

The spectrum is completely different. The Prime 16HD Reef has a blue/white spectrum optimized for coral growth. The Prime Fuge has a red-dominant spectrum optimized for macroalgae photosynthesis. They are not interchangeable for their primary function.

Should I run the refugium on a reverse light cycle?

It is recommended. By turning on the Prime Fuge when the display lighting is off, macroalgae consume CO2 at night, stabilizing pH and preventing overnight drops. The Mobius app makes it easy to program this reverse cycle.
