Hammer coral bleaching

[fronty]

My hammer coral is losing a lot of color. My lights are at 15%/23%/23% (I have an AI sol nano). My tank is a 12 gallon Fluval Edge. What else could be causing the bleaching?

Thank you

how long are you running your lights? How high up do you have the hammer placed?

is it new to you? if not, did you recently switch to LED?

I found that when I first switched from t5 to LED, my euphyllia lost a lot of color (becoming very transparent) but always stayed fully open and looking happy. within 4-6 weeks they regained full color and never looked happier.. I'm not the first to experience this, I've heard it from several people and it's simply how the coral adapts to the change in lighting. it can take a while for the color to bounce back.

I'd keep it well fed and don't blast it with light, it should recover easy enough..

I'm running my lights from 8 to 8. I have it set to ramp up and then down. I have it set to a pretty low setting. I read that too much light can cause bleaching.

It is placed near the bottom.

I've probably had it for 6 to 8 weeks.
