Uknown Favia Issue?

[blakemc91]

Hello,

I have noticed my favia has started to develop white rings around the inner polyps over the course of the last 4 months. If I look back at photos I notice it is happening gradually over time. It definitely is showing signs of overall growth as it has attached to the rock off of the frag, but I cannot find any posts with this white "halo" effect.

Wondering if anyone else has seen this and it is a sign of new tissue growth or something more ominous, like too much light or some type of necrosis.

Parameters:
Salinity: 1.025
Nitrates 10 - 15 PPM
Alk - 8.5
Calcium - 400
Ph - 8.15
Unknown Par on lights
Flow - indirect flow

Looks normal to me.

Colors will morph slightly in certain given conditions in all aquaria

like too much light

Here are pics of two of my Favia right next to SPS corals.

I don’t think you have too much light.
