Anyone know what's this macroalgae and is it suitable for phosphate and nitrite reduction in refugium.

i wish i could say i knew but i don't...

 

[calvinci]

this isn't some rare macro, in my town, 80% of the LFS is selling this and claim that better than chaeto, that's why I thought someone have experience with it.

That is some sort ofCaulerpa. It kind of reminds me of C. serrulata. This genus is commonly used in refugiums but may die off if it decides to try to reproduce.

I don't think it's C. serrulata as it has a smooth edge leave while C. serrulata should have saw tooth leave.

I think it's maybe Caulerpa brachypus f. parvifolia (Caulerpa parvifolia).
