Coral Bleaching

[DJ88]

Hi Sam,

I have had corals bleach but it usually ocurred in new corals I just put in my tank. Fragged or wild harvested. Unless my tnak crashed. That is a whole other story.

How long have you had this coral? Was it bought as a frag from a fellow reefers tank? Or a store bought captive harvested colony? Those are inportant bits of info that may help us help you.

As for the info you provided all I see is that to me your salinity, alk and temp. I keep my salinity at 1.025-27. Alk is at 12dKh. The temp swings are pretty noticeable as well. But I keep mine within 1.5 (81.5)degrees at all times. Do you have your heater set correctly?

What kind of lighting do you have this coral under? What kind of water flow do you have in your tank? Is there a powerhead hitting it directly adn constantly.

Take a look at what I mentioned and I am sure some of the more knowledgable guys here can help a bit more..
