What kind of Lagae

[cgr124]

Hello I have this brown string algae all over my GSP causing it to stay closed. I don’t see it elsewhere in my tank, only by my GSP. Does anyone know what this is? I assume it’s a brown hair algae but I’m not sure. Is there a way to get rid of it? I tried basting and brushing but it has t worked. Tank is 4 months old and parameters and nutrients test ok? Thanks

What clean up crew are you running? You need some hermit crabs and snails to keep it in check.
