Bubble coral not opening

[plunderisley]

I got some bubble coral about 6 days ago from the LFS. I brought it home, acclimated it (along with all the other new pieces) and added it to the tank. After about 15min all my new corals started opening up and within a hr all the corals except my bubble was fully opened.
I placed my bubble coral on the far right of the tank away from any high/med water movement and in some shade. It started opening up a bit, but was getting blown a bit so I moved it to the other side of the tank with a low flow and it opened up a bit more. But so far, it looks like this:

What could be wrong? What could be causing it to open?

Any thoughts on why it won't open?

Well I have some in a small LPS tank in pretty hardy flow, and it seems to do fine. If this is an LPS dominant tank and all other LPS are fine I'd say your water parameters are OK. Seems when i first got mine and i put in tank it did well, but next day I removed it to attach to rock and it got a little henky for a few days. But moderate light and water flow should be OK. Stop moving it around for a couple of days and wait and see. Might just be stressed from handleing it. If it hit some air going in and out of bag ect...

I started mine low and slowly moved it up. Its about 6" from the top with low flow. I'm running a 6bulbt5ho fixture. You could also try feeding it. That might help.

Just give it time. I had the same issue with a bubble. It took over two weeks for it to open the way it had in the LFS tank.
I was worried at first but now it is doing great.

low flow is the key to bubbles.

I'm a outsider looking in on the bubble coral, I don't have one. Honestly asking, the brown on the skeleton isn't a cause for concern? Or is that normal for bubbles?

Relax....its getting acclimated. It takes some time on some corals, other not so much. Just leave it be and dont move it. Give it time and rest, it will come around.

I've never been successful with bubbles. I have Hammers, plates, trachs, and monti's. Some people say they grow like weeds. Mine just slowly decline. I've tried two BTW. Maybe I have just too much flow.

Yea, once I started keeping sps, I increased the flow rates in the tank in a major way and now some lps corals have trouble because they just wont open up all the way. I gentle brisk of flow is whats required and now I have created a small low flow area for these corals

I have said that in several occations. My experience is that bubbles do not accept phosphate resins together with activated carbon. Once I removed the activated carbon everything goes perfect with bubbles

Maybe you're onto something victor. I've always run carbon with GFO.

Interesting. I am running only carbon media.

Why don't you try to take out carbon for a couple of weeks and see what happents.

Take the carbopn out change the water (to introduce oligoelements in the tank), and wait.

Bubbles can react quickly to it and improve
