Hard to tell from the image, can you take a better one in focus?
Is it branching or non branching, looks like it might be branching, so could be Cladophora.
Either way, the usual applies. Clean the filter, and ensure your CO2 flow and distribution are on point. Do a substantial water change etc...

I think it is spirogyra, long threads like human hair that can be foot long. I have it in my window sill planted shrimp bowl that receives direct sun light. It thrives in the same conditions as for healthy plants and the lush green can be attractive in small quantity. Shrimp and snails don’t eat it, and probably no algae eaters will. It’s easy to remove physically as it comes off in strands that don't stick but can entangle plants. I do a physical removal every few weeks but it returns to reconquer.
I read that API Algaefix is effective against spirogyra but I don’t dare to try as the label says it will kill shrimp. I haven’t tried Excel or peroxide either even though proper dosage is said to be safe for shrimp.
But if you don’t change the fundamental, it will return. I have sunlight and no CO2. Pond people have to deal with it often as they can’t reduce sunlight. What’s your growing conditions.Yup have the same problem. Its tangled into roots of the other plants and smothers the smaller ones. From what I can find in google its best to dump all the plants and start anew.
That would be my guess, partially based on colour. Cladophora is <"quite tough"> and difficult to pull apart, it also often feels a bit "gritty" when you roll it around in your fingers.so could be Cladophora.
