Adding a refugium to an existing setup

[Nanoreefboi]

So I have a Nuvo 10g tank, which is currently having a little problem with some hair algae. I use pure 0 tds water, and a good water change schedule. However, I am having trouble getting rid of the algae. All of the corals are healthy and colorful, but the algae can get unsightly at times. The only form of nutrient export I am running is a protein skimmer. I am thinking of adding a refugium with chaetomorpha in one of the chambers of the built in sump. So, I have the following questions: Can I add macro algae into a one year old tank? Will I need to do something to give the newly added macro algae a chance to obtain nutrients against the hair algae, like a display blackout? And lastly, will the chaeto outcompete the hair algae for nutrients?

What is your po4 and no3 at ?

I don’t know exactly as I haven’t tested the past week, but last week it was PHOS: 0.02 ppm and NITRATE: 1-2 ppm. This can be unreliable as the algae can “lock away” some nutrients.
