This is a new one I haven't run across before. Not sure if it's nuisance or a good macro. Grows pretty fast grows from a single point. Spreading through the tank though, so i'm actively trying to limit it.

@Rcj520 what determines nuisance to you? Marine Plants in the Aquarium macroalgae, marine plants, caulerpa, refugium substrate, marine macroalgae for sale www.marineplantbook.com CYSTOSEIRA SP.​

Species of the brown algae Cystoseira feature tall, stiff branches, typically light brown in color, with some air bladders present on the outer branches. This species is often confused with Sargassum, but lacks any flat blades, instead having tight toothlike appendages. This particular algae is rarely seen in the aquarium trade, but one variety Cystoseira Myrica, does make seasonal appearances, as it iss native only to Florida and the Bahamas. It is not as demanding in its nutrient needs as Sargassum is, due to its smaller size. It can make an interesting addition to a marine aquarium, but requires a brightly lit environment. Not palatable to most fish.​

I don’t think this is Cystoseira, which appears to be more “structured” than @Rcj520’s algae for a lack of a better term. There are some Dictyota species that come close to resembling OP’s algae, but I am still stumped.

I don't know for sure, but the most likely candidates seeming to me are (in order):
-Kappaphycus sp., possibly K. alvarezii
-Pseudochnoospora sp., possibly P. implexa
-Euchema sp., possibly E. denticulatum
-Hydropuntia sp., possibly H. edulis

Also, is this algae tubular or does it have flat, ruffled blades.
