Help with Colony Polyps!!

I have a LR covered with colony polyps! A couple days ago, after I did a water change, the polyps stopped opening. They are all closed up and today I found a few have detached from the LR.

I have no idea what is happening as all my other corals are fine. My water quality is fine with PO4=0, NO2=0, NO3=20, CA=400, KH=10, MG=1130 and Ph=8.1. Is there anything else I should look for?

Did this increase, decrease, change at all during the water-change?

I haven't seen anything kill this stuff faster than abrupt changes in specific gravity.

Sounds like you've lost her. However, there's a chance it will "regrow", for lack of a better word. Just keep your light up. Its strange tho, you have pretty much exactly the same water stats I'm sitting on...

The salinity has been pretty much constant over many months. The funny thing is, there is nothing wrong with my other polyps and soft corals.

Here is a picture of the polyps. As you can see they are all closed up and some are coming off. However, I am not sure if they are coming off naturally. I have spotted my yellow tang pecking the closed polyps. So it might be coming off because of his behavior which is not normal for him.

How much of a water change and was it aged salt water. Sometimes fresh made salt water has a caustic effect when you don`t age it. Just an idea. Good Luck

This started happening before I changed water. I always use aged salt water.

I had this happen with a salinity change problem but all came through. It lasted almost a month though. You did not change salt recently did you?

Otherwise just watch them and ride it out. You might check the tank and make sure nothing is pestering them.

Thanks Ellisz! I'll just keep an eye on them. No, I did not change salt.
