Lots of water changes is probably the best bet.
IME with algae, a lot of the time it ends up dying back after a while because it starved itself of nutrients.

Water change, no feeding for 1 week, No overhead tank lights for 1 week, cover tank for the tank for a few days.
going forward reduce tank lighting to 2-4 hours per day

Something that might be helpful is to find the root cause, or it will constantly return
Most of the time green water is a symptom.
Lights could be on too may hours.
Your tank could be getting excess sunlight.
Overfeeding.
Algae also need food, which usually comes from nitrate, and other parameters which usually comes from too few water changes.
What is your nitrate reading?
How often do you do water changes, and how much per change?
Also what and how many, and what size fish, in what size tank?

I’ve had this happen before it’s simply an algae outbreak, I tried all the above and personally it’s never worked for me. In the end I took out all decor and water and just washed all the decor and refilled it. But if there’s fish in there and you don’t have another tank you can put them in a bucket with clean water.(make sure parameters and temp are good)
I've dealt with two outbreaks of green water in years of fishkeeping, and both times my experience was like Kolton13 above: nothing worked. It was like a tire fire. I could knock it back, but it would just return. Went on for months. The only thing that definitively got rid of it on both occasions was doing a big water change and then running a UV filter for two weeks.
A Diatom XL or other DE filter will clear up green water in a matter of hours. I run a DE filter full time... the details are in my signature.
