Having an issue with some corals darkening.

[Luis's Nano]

Hello, I'm having a hard time figuring out why some corals I have in my tank get darker over time. I haven't had any die but have had issues with them getting darker and losing their pop! Any help would be appreciated.


Alk- 7.8-8.5 (Hannah)
Cal-400-430 (Hannah)
SG-35.0 (Hannah)
Phostphate- 0.06 (Hannah ULR)
Nitrate- 2.5-5 ppm (Salifert)
Magnesium- 1400 (Red Sea)

I do run gfo/carbon mix 24/7 and chemi pure blue.
Running chemi pure blue alone kept water clear but I needed help with phosphates. I feed a cube of LRS reef frenzy every other day. Reef roids once per week. Maybe over kill on the chemi pure and reactor?

Colors look nice ..... What lights are you running and I dropped my po4 from 0.06 to 0.03 and colors look great but what works for one person might not work for the next

I am running a radion xr 15. Most of the tank looks good. Not much color loss but if you check out the dragonfruit montipora and the mystic grape facial. They are getting darker. The monti used to be a nice bright pink. Pink like the growing portion of it. The favia is slowly losing its green outer rim. I can't figure out why. I also have a wwc ultron favia that used to have the nice silver center with reddish flesh with yellow gold and now it's sort of blah.

Try lower your phosphate under 0.05 and see what that does
