My Favia is getting white around the edges

Does anyone know what can cause this. Picture is tough to tell but you can see it on the edges...thanks

To much light, ALK swings, bacterial infection. Move to lower light area and give it some time.

Check your alk, move it to an area with lower light and flow. And feed, in my experience Favias recover well when fed regularly with a fine food or some type of chopped up mysis. They love to eat and respond well when fed. But if it's not getting any form of nutrients, or there's a lack of them, this could possibly be the corals way of self preservation through self necrosis in an attempt to save itself. Smaller the coral, less nutrients required to sustain the colony. Hope this helps.

Thanks...I moved to a partial cave and started to feed. I have not been feeding.

Alk is 10.6

10.6 is ok. Know that the best time to feed Favia's is about an hour after lights out. I get full sweeper extension at this time, makes feeding more productive

Your very welcome

Now take a pic with whiter light so I can actually see it-lol. Favia's are my fav! I have a few different species.

I also forgot to mention, when a coral like this starts to recede from the edges, whether its a necrosis issue or bacterial, don't expect results quickly. First thing to look for is the recession of the tissue to stop, then the next thing to look for is the edges of the tissue start to push out, puff up and eventually start to grow out again over the previous skeleton. It can take time, it took some of my corals months to get back to normal, but feeding regularly (i.e. daily) helped tremendously.
