Macro Algae Lighting

[Schraufabagel]

I currently have an AI Prime 16HD. I have had calcified macro algae’s in my tank for about a week. They had arrived in the mail after a week and a half of shipping (it was really late). They were still green when they arrived. However, they are now pale and I’m concerned they might be dead or dying. I am in a ugly phase of my tank, since it’s still only 2 months o

My current spectrum settings are
UV 40%
V 40%
RY 60%
B 100%
G 30%
DR 20%
ML 0%
CW 100%

Should I change my spectrum settings? Or are they dead and I should just replace them?

Also, my nitrates are in the 10’s. Ca is 420

Have you tried upping the flow and lifting intensity around the algae?

I have not. Should I up the general intensity? Or just the red and green channels? Flow is currently at 1000 GPH, I’ll up to around 1500

From what I see in my macro algae tank, macros sometimes turn pale/white but they somehow recover or grow new branches after a while. I was worried initially but I let them be and they seem to be growing now.

I’ll wait another few weeks. I upped the flow for now. It was kind of low
