Help green hair algae
 

So I been battling a green hair algae outbreak for two months, not sure how to get rid of the stuff. I have been doing water changes with rodi water ever other week, I tried changing feeding in the tank and I also reduced the hours my lights are on....anyone know of any product I can add not sure what else to do at this point. Tank has been running for 4yrs never had this before, and all readings are showing normal levels

Trochus snails, sea urchins are working for me and mine is almost gone. Hand pic out as much as you can, urchin leaves bare rocks white runways as it moves around. I also have an emerald crab not sure how much he eats.

If you have a sand bed it maybe full of stuff causing nutrients to leach out slowly and then they are consumed by the gha. So vacuuming it helps. It will go at some point if you keep fighting. There is a product called vibrant that can work with gha and bubble algae. I try and use products as a last resort.
