What are these algae?

[Alex_23]

Hello!
Recently this type of algae started growing right under my light. Does anybody know what are those? Are they bad?

parameters:

alkalinity: (trying to increase it slowly) 6 dKH
salinity: 34 psu
calcium: 390mg/l
magnesium: 1318 mg/l
phosphate: 0.1 mg/l
NO3: 15 mg/l
NO2: 0.05 mg/l

Thanks for any response!
Alex

Macroalgae isn't my strong point, but I feel relatively confident it's from the taxonomic order Ectocarpales, possibly something like Leathesia difformis or a Colpomenia sp., but I don't know for sure.

It seems like it's all growing from the same area rather than from random clumps in your tank, so I'd guess it's alright even if it's fast growing, as you should be able to maintain it pretty easily from what I can see of it's growth (i.e. it doesn't look like it'll take over your tank, but it does look like you may need to trim it back every now and then).

You could try posting in the macroalgae forum and see if anyone there knows what it is for sure.

Hope this helps!

Hey! Thanks a lot for your answer. Helped me a lot ! I will just let it grow then and trim it sometimes.
Thanks!!
