Gracilaria

Gracilaria is the gourmet red macro algae every refugium (and every tang) wants. Its bushy, branching clumps pull nitrates and phosphates from your water around the clock, delivering natural nutrient export while providing dense shelter for copepods and amphipods that feed your reef. Varieties like our Atomic Broccoli sparkle with ruby color under refugium lighting. Culture is effortless — moderate light and enough flow to gently tumble the clump — and regular harvests both export nutrients and supply fresh, vitamin-rich greens your herbivores will devour.
