SPS bleaching question
 

Hi there, I've got an Emerald Sky SPS coral and I moved all the spa corals up from the bottom of the tank on top of the rocks. I was told that this coral likes bright light and it is a 5 inches below the surface. I use sun brite LEDs for lights. Only this coral has gone white at the top tip. Has anyone else experienced this? Ive moved him down to the sand bed for now.

Any help would be great.

Move them slowly up. Maybe a third of the way each week

Have you got a picture? white on the tips could be new growth

What I do with new frags (if this is an option for you) is put them on my magnetic frag rack and move them up a few inches each week. Or you can just move them up the rock work the same way

+1

The colour doesnt seem very emerald either. Do you think it is sick? All of the other sps corals have their polyps out. I've moved it to the sand bed now too.

I've had an ich infestation and I've been treating with Herbtana for a week but I don't think that there was a change once I started treating it.

Sorry to say this Dude,

But the frag is RTN-ing I don't think you can do anything to save it

Ya, agreed. It may stop, but probably not.

It mist cases once it starts your hooped. But I've crazy glued over the affected area a few times and while unsightly, its saved the frag. Maybe give it a shot.

I had a similar sps frag do the same a year ago. I just let it be and it recovered, slowly. Lost most of it though. Exact same scenario with my birdsnest.

Crappy... Is there anything else I can do? What caused the rtn? Is it contagious?

I was told to double check my parameters which I did and everything seemed to be in check. Ive never been able to find a definitive cause. Couple things i did around the time of my RTN that could have contributed was changing my light fixture t-5s, beginning to run GFO.

It can be contagious.....if the flesh that is falling off comes in contact with another SPS it can spread.

And as for what caused it....sometimes it just happens for no reason.....but I would say the stress do to being moved to a new tank caused it. Don't fret over it, has happened to me over the years many times.

Should I take it out of the tank?

If you have the equipment to do so cut it just below the white fleshless area. It may stop the rtn

What do I need to use? Can I clip it underwater with clippers? Do I need to stop it from "bleeding"?

I would blame GFO.

Dropping PO4 too fast will cause your SPS to RTN.

Start with 25% of the recommended amount of GFO and work your way up slowly.

Sorry all I meant was a bone cutter

Can I just snap it with pliers? Or garden shears?

I use side cutters
