Slowly bleaching favia

MattieH · 04/17/2019, 06:39 PM

This favia has been in the tank for maybe a year. It's looked great until about a month ago, when it started to lose color. It's getting lighter and lighter, and now it's starting to recede at the edges. All other coral in the tank seems just fine. I've attached before and after pics. Any measures I can take to try to save this favia? Thanks in advance!

Has anything changed recently in your setup? New lights? New lighting period? What are your latest parameters?

I found my Favia started to fade after 4 months or so and I guessed it was getting too much light. I moved it a bit lower and it started looking happier within a couple of weeks. It has now been there for 10 months or so and is growing well.

Did anything change with your light intensity?

Actually, I lost an ATI bulb about the time this started happening. So if anything, it got darker in the tank. I have all new bulbs on order but haven't started replacing anything yet.

At 80ppm nitrate, overtime, it will bleach, not a light issue.
