Tink March 24, 2013 Share March 24, 2013 I noticed my stylophora was looking rough today. It was fine yesterday, and I'm not sure what's going on. Here's a picture of the damage. Any ideas? Link to comment Share on other sites More sharing options...
Coral Hind March 24, 2013 Share March 24, 2013 Can you explain what exact damage you are seeing? I see white tips which could be from too much light or from rapid growth but I'm not sure if that is what you are talking about. Link to comment Share on other sites More sharing options...
Tink March 24, 2013 Author Share March 24, 2013 (edited) I was worried about the retraced polyps that look black-ish. On the right branch you can see one almost looks like a gaping hole? Here is a view of what I'm talking about Edited March 24, 2013 by Tink Link to comment Share on other sites More sharing options...
Kingumar March 24, 2013 Share March 24, 2013 (edited) Depending on what exactly that coral looks like. Most of the time, white tips are the signs or coral growing. As stated above. Edit: looks like the coral has lost some flesh there. Hmm Edited March 24, 2013 by Kingumar Link to comment Share on other sites More sharing options...
Coral Hind March 24, 2013 Share March 24, 2013 The polyps could be retracted because it grabbed something to eat. Maybe something brushed up against it and caused it to retract. Or, you have a fish or something in your tank which is picking on it. Just rule out some things, what fish do you have? What type of lighting do you have?

Tink March 24, 2013 Author Share March 24, 2013 Here's the latest water params: SG = 1.026 pH = 8.2-8.4 Ca = 440 KH = 8.5 PO4 = .01 Mg = 1320 NO3 = 0 Link to comment Share on other sites More sharing options...
Coral Hind March 25, 2013 Share March 25, 2013 Your parameters look good. Are you using a refractometer for the SG, make sure it's calibrated. The fish list seems fine, no polyp nippers on it. That seems like a very blue color combination for your T5's. How long are the ligths on for? How is it looking today? Link to comment Share on other sites More sharing options...
Tink March 25, 2013 Author Share March 25, 2013 Yea, the refractometer was calibrated just a couple weeks ago. I also checked with my back-up to confirm. Lights are: 2x Blue Plus = 8.5 hours a day Actinic and Coral Plus = 6.5 hours a day Here is an updated picture. I blew it off with a syringe last night to make sure there was nothing on it, and to cause it to retract so I could better see the damage. It has yet to fully reopen.

Coral Hind March 26, 2013 Share March 26, 2013 I agree with Z2K, it's pretty normal. Just kick back and observe. There doesn't seem to be any tissue damage other than the color is kind of light, either not enough or too much light maybe. I think you might have a Pocillopra.
