Zoa bleaching?

[Nfd552]

the center of some of them are white. Are they bleaching? Too much light? They have been fine where they are for a 6 weeks. Moved up gradually. Params are all fine. Only change was adding a algae reactor for 10 hours at night.

If they were bleaching I'd expect to see them lose color in the "body" as that is were most of the zooxanthellae live. The center is their "mouths ".

Also, a lot of times when you see the body extend like that, it means they're reaching for light. What kind of light are you running?
