Favites Bleaching

[FreshCoastReef]

Hi all,

I was away over the week of the 4th, and when I came back home I noticed that my WWC Festivus Favites has lost some color along the top edge. It has been in my tank 4 weeks now.

Parameters are:
PH: 7.9
Salinity: 1.025
NO3: 0ppm
PO4: 0ppm

I am running my AI Prime from 8am to 6pm with the following values:
UV 118%
V 118%
RY 88%
B 88%
CW 68%
R 8%
G 8%

Any thoughts on the likely contributing factors to this change in color? and potential solutions?

Kind of looks like it has it's feeding tentacles out? Low nutrients might be too low? Try target feeding it live or froozen pods or planktonic algae.

0 nitrates and 0 phosphates could be big factor especially if not target feeding or it can feed itself grabbing food.
To much light or not enough.
To much flow or not enough.
Fish nipping at it.
These are common culprits among others I read often

Good luck

Thanks @KrisReef I had a similar thoughts and tried some target feeding earlier today.

You have zero Phos and nitrate and in essense they are lacking nutrients. Additionally, they do best at lower third of tank but not at sandbed under moderate light and water flow with feedings 2-3x per week with mysis or brine shrimp.
Salinity 1.025
Temp 77-79
calcium 400-440

Thanks for the feedback @ying yang

Thanks @vetteguy53081 I will look into improved placement as a possible solution.
