At AlgaeBarn, we meticulously treat, quarantine, and inspect all our CleanMacro™ Live Macro Algae to ensure the highest quality and cleanliness for your aquarium. While no macro algae can be guaranteed completely free of all hitchhikers or spores, our process is among the most rigorous in the industry—and every order comes with our 100% Alive On Arrival Guarantee.
With its fiery red to deep burgundy hues and flame-like, tapered fronds, Pom Pom Gracilaria brings vibrant color and texture to your display tank or refugium. It’s not just eye-catching—this macro algae is also highly effective at nutrient export, helping reduce nitrates and phosphates in your system.
A favorite among reef keepers, it also doubles as a nutritious live seaweed food for herbivorous fish, especially tangs. Grown in your refugium, you can trim and feed excess growth as a healthy treat for your livestock.
