Pesky hair algae

[bookeey517]

What kind of algae is this and how to I get rid of it? I find my self cleaning it with a toothbrush about once a week and it grows back every time. Anyone have a solution?

Seeing no coral on this rock, I would place it in a container of tank water and pull off as much as you can by hand and scrub the rest with a firm toothbrush and some 3% hydrogen peroxide.
Return to tank, reduce white light intensity and number of hours of white lighting and add some snails such as :
Astrea
cerith
turbo grazer
trochus

A Pencil urchin

8-10 Caribbean blue leg hermits

Are you using RODI water or tap water from the faucet ?
What is your phosphate level?
Is tank at or near a window?

Thank you for your quick response!
I am using RODI water and my tank is not next to a window.
the phosphate level is 0.25ppm.

would you recommend the lettuce sea slug? People say it’s good for hair algae but I’m afraid they may be fragile.

Your phosphates that high is what is causing the algae issue, lower those and the root problem goes away
