Hair algae or?

I am trying to figure out what algae this is. It was green other day removed a lot but two days later it’s back even worse. I am trying to figure out how I get rid of this.

Sorry this better

Looks like GHA. What are your parameters? Manual removal and water changes will help. Do you have a Refugium? This can help outcompete the GHA in the display. What does your CUC consist of ?

manual removal is going to be the biggest contributor to fighting it.

Yup, that is GHA. Check your parameters (NO3 and PO4), but be prepared for artificially low readings with an invasion that severe. Get yourself a stiff bristled brush and a siphon. Manually remove as much as possible, then scrub at the rocks using your brush while siphoning out what comes off. Perform a WC.

What are your nutrient export methods? How much ate you feeding? What are the stocking levels of your system? How large is it?

I will check my parameters tomorrow. Would a sea hare benefit if I add one? I basically brush it of in tank and siphon out so I guess thats not a good way of doing it. Maybe spreading it?

it wont spread it, but if algae dies off in the tank, it feeds your N/P which will just attribute to algae growth

Sorry, didn't mean to leave you hanging. I got distracted. I wouldn't add a sea hare. Once you get your nutrients and algae issues under control, food for it will be at a premium. You don't want it starving on you.

If you have room put in a sea hair or a rabbit fish

I rotate my hair from DT to sump to 3rd "QT" tank
