Tis Halimeda sp. macroalgae... very nice.
Halimeda calcareous algae grow well in environments with high calcium, medium light, very low levels of nitrates and phosphates, and low amounts of iron in the 0.05 ppm range. These macroalgae grow upright, many preferring sandy bottoms for attaching their fiberous rootlike holdfast structures, but some such as the H. discoidea and H. optunia may appear on hard bottoms and live rock as well. In nutrient rich reef aquariums they may require thinning:yeahdude:
Halimeda. Just be careful as that can play with your calcium and alkalinity levels
Sorry, just imagining how it will play with calcium.
