Pull as much as you can by hand and then reduce white light intensity or amount of hours of white lights and add the following snails and cleaners:

4 - astrea
4- Turbo Grazer
4- trochus
4- ninja star or one fighting conch

1- pencil urchin

6-8 carribean blue leg hermit snails which are tiny

Agree with all mentioned above. Also a Lawnmower/Starry Blenny or Foxface has helped me out a lot too.. don't knownif they are on your stock list

You really need to pull as mentioned but reducing red and green lights are what will help. White contains red and green, true, but algae also utilizes blue also.
So don't think that turning on blue lights for a couple weeks will help. What grows coral, grows algae.
Best bet, manually pull, even if you do in sections. Needs to be done multiple times a week. Add snails, Mexican turbos are great for hair. They will process it down for you. Keep checking nutrients and keep them in check.
