Macro algae are one of the most effective and natural ways to improve reef aquarium stability, nutrient control, and biodiversity. Whether you're building a refugium, creating a lagoon-style aquarium, or looking for decorative marine plants, macro algae can provide both practical and aesthetic benefits. At Charterhouse Aquatics, we offer a range of marine macro algae species suitable for refugiums, nutrient export systems, and display reef aquariums.
