Is grape caluerpa a good choice for macroalgae in my refugium? I dont have another algaes available to me where I live and I dont feel like spending $20 on a bundle of algae when I can get a nice clump of grape caluerpa for $2 a clump. I was told its very invasive but I dont have anything else growing down in the refugium. I just need something that will really absorb nitrates.
