Hard Green Algae Won't Go Away

[Ippyroy]

I have hard green algae on all of my rocks for over a month. I do weekly 10% water changes. I have around 20 corals, zoas, palys, and favias more the most part and one bird's nest. My PO4 is .10 and my NO3 is around 5. How can I get rid of this stuff?

Hi,

Can you post a pic? Coralline can start green and turn pink/red over time.

green coralline grows slow. My rocks are covered. i have confirmed what it is, but it should go away in a couple of weeks. I'm over a month with this stuff.

I have shortened my light period and decreased my feeding. I am starting to see larger pieces of algae growing and will be increasing my CUC. Other than that, just keep NO3 and PO4 in check and give it time.
