Green hair algae

I have a 150g tank with a sump and decent flow I just brought my phos to .1
I have 3 turbos urchin 3 emerald crabs and I’m curious what can I do to get rid of the hair algae efficiently because I’m tired of looking at it there are a couple of different locations and they are a decent size to the point it’s growing on my gsp coral

You need a lot more CUC in there.
Get more snails, more crabs, more of everything. Conch is another good option too.
What are your nitrates?

Nitrate 39
Sadly I had a conch but he dug into the sand a couple of weeks back and I never saw him again I moved a lot of live rock and I may have pinned him somewhere another concern of mine

What do you mean you just brought the phosphate up to .1, why? With nitrate at 39 your water is very nutrient rich. The easiest way to get rid of hair algae IMO is to starve it out plus manual removal plus more algae grazers.

I brought my phosphate down from .5 to .1
I appreciate the info brother
