Help! Pocillapora Bleaching!
I have a giant Pocillapora coral (~7" across) that has begun to bleach. It sits at the top of my tank about 5-6" below the lighting. I've always had four 96 watt VHOs. I use to have a single 250 watt MH (6,500K). Around Christmas I added a second MH fixture, but switched to a 10,000K lamps. All my other corals are doing fine and are growing as usual.
Has anyone had any experience with "established" Pocillapora coral bleaching? I got this one from Terry over a year ago as a piece of rubble that was at the bottom of his tank. It has done very well until now.

Wind me up!
Is it bleaching or browning? IME they brown easily when lighting changes. But they also can recover well. Adding the extra halide may indeed have stressed it... if you think it is bleaching and not browning then you can move it lower in the water column for a few weeks and see how it does.... It should be fine in high light in the long run though......

It is bleaching! You can't tell from this picture because the bleaching is on the top. The polyps are still there, but they're a ghostly white. I'll try to move it to the bottom of the tank. I don't really have the room to make the move. I'll figure out a way to get it done though. Thanks!

That's a really good question! I added another fan to the canopy when I added the light. Before the light, the summer time temperature was about 81F and now during the winter it's the same.SaltnLime wrote:this may seem like a silly question, but what is the temperature of the tank now, after adding the new halides? Significant change even if within the safe params? Other tank params good? Just curious.....
I am worried what will happen this summer though. My house is staying a consistent 72F during the winter, but during the summer I peak to about 76F-77F. I'll be adding a fan to the sump then!
I haven't checked my nitrates for awhile, but other than that... yes they're all good. I'll check them today just to make sure.
