Red zoas turning brown and losing skirt color

[Danmuges]

I've asked on here before but didn't have photos. Hopefully this will help. I'm having problems in my frag tank. Certain zoas such as the fire and ice, sponge Bob and scrambled eggs, Emerald on fire (see pics) are losing the color of their skirts. It's mainly noticeable on the reds which are turning brown but whenever I return them to any of my other tanks the colors return over time. I test this tank weekly, feed ab+, reef roids and its the only tank I have problems with. All of my other zoas are fine. Has anyone had this happen or know what the problem could be? Could I put it down to gfo? I don't run that on the other tanks.

Nitrates 11.5
Phosphate 0.10
Alk 7.9
Calcium 440
Magnesium 1480

Lighting between 70 and 150 par
Ai prime all blue, violet and uv spectrum

Have you considered adding any white to your lighting spectrum?

I have been running 7% whites. Still not looking great

Hello all I'm. Still having these issues

Not 100% sure but I think the phosphate may be a bit high which could be browning them out? Again not too sure

i cant get my phos below 0.15(hanna) and run gfo and now a ats....my zoas are plump and colorful so i dont think it would be affecting them..

I'm having the same problem with the scrambled eggs in 2 of my tanks. Phosphates in both are 0.06 and 0.08

Do you target feed your zoas? If so, what are you feeding?

Did you figure out what it was? The same happens in my tank.

Figured out the problem. Salinity was 1.030
My calibrated haha salinity tester was reading 1.026. Bought a refractometer and read 1.030. Since lowing salinity everything came back to normal

My salinity is good. I however don’t have a phosphate test kit yet.
