Can someone help ID this algae and tips to get rid of them

[Minh Chi Nguyen]

Hi,

Can someone please help me ID this algae please? I have had them for about a month. Nitrate tested 0 and I have been using chemi pure blue nano. I also have a refugium reactor running for 4 hours (was running for 12 hours, reduced to raise nitrate but did not elevate). I'm leaning toward dinos (why I tried to raise nitrate) but there are no bubble coming out from them. It might be diatoms but nutrient is low. Thank you in advanced for your time.

They look sorta green in the pictures, but they are brown in real life. Would that makes a different?

No difference. GHA is a loos term that cover a bunch of green and brownish looking algae that are similar in structure. see this reference:https://www.reefcleaners.org/nuisance-algae-id-guide.

Getting rid of it varies. You need to have some clean up crew, snails and such. Algae eating fish help such as tangs or lawn mower bennies. But there is no one species that you can add that will automatically take care of it. You need to help them by keeping your tank clean. Physically remove the algae if it gets too long (CUC tend to eat short algae but not long strands). Blow detritus off the rocks periodically so it can get captured and removed in your filter media such as a filter sock, etc. Make sure your phosphate and nitrate level do not get out of hand. One thing I have learned is that when the algae gets out of hand it actually captures detritus and creates a local food source. As the detritus decays it releases nutrients the algae can use.
