boricuareefer Posted October 31, 2013 Share Posted October 31, 2013 Newbie here. I have a duncan that has been closed for the past week and a half and the body has turned from it's original brown color to almost complete green (see pic). Anyways I was wondering it this is something I should be concerned about and if anybody has any suggestions. Here are my water parameters as of today Nitrates 0 Ammonia 0 Nitrite 0 Calcium 450 PO .09 Alk 8.2 Salinity 1.025 PH 8.2 Quote Link to comment Share on other sites More sharing options...
victoly Posted October 31, 2013 Share Posted October 31, 2013 Not good. Looks like it's on it's way out IMO. Once you start getting algae covering the entire skeletal structure like that, i've never had luck bringing them back. Nothing about your params look off, but then again its usually swings in parameter that do the damage. How is the temp in the tank. Other inhabitants doing ok? I'd try scrubbing off the algae with a toothbrush and move it to a more shaded area. Quote Link to comment Share on other sites More sharing options...
boricuareefer Posted October 31, 2013 Author Share Posted October 31, 2013 Oh-uh. Not what I wanted to hear . Water temp is currently 78 degrees. Everything else is the tank looks great. I'll try the toothbrush trick maybe later tonight if I'm not too tired from trick or treating with the kids and celebrating my birthday.

jestep Posted October 31, 2013 Share Posted October 31, 2013 Has it been in the tank for awhile? Did it have good polyp extension before it closed up? That's definitely algae on the skeleton. Quote Link to comment Share on other sites More sharing options...
Bogdan Posted October 31, 2013 Share Posted October 31, 2013 It could still come back. I would try first turkey buster to clean/blow the algae off. Tooth brush may be the last resort if the buster doesn't work. Also I would place this coral somwhere where there is a more flow. Quote Link to comment Share on other sites More sharing options...
esacjack Posted November 1, 2013 Share Posted November 1, 2013 (edited) .. did your flow change? is one of your pumps possibly not working? Edited November 1, 2013 by esacjack Quote Link to comment Share on other sites More sharing options...
boricuareefer Posted November 1, 2013 Author Share Posted November 1, 2013 Has it been in the tank for awhile? Did it have good polyp extension before it closed up? That's definitely algae on the skeleton. It has been in the tank for about 2-3 months and it had good polyp extension, yes. Quote Link to comment Share on other sites More sharing options...

Neon Reefer Posted November 1, 2013 Share Posted November 1, 2013 LPS vcan be a fickle creature sometimes, and for no apparent reason just crash. And Duncans are quite sensitive to lots of things like all stonys. But they especially don't like SG changes that some other LPS will tolerate. Your PO4 is a little high @ 0.09 ppm, I'd try to get that down a bit although for LPS it really shouldn't matter. It may be a problem for more sensitive SPS though. It does look pretty far gone but you never know. Quote Link to comment Share on other sites More sharing options...
esacjack Posted November 2, 2013 Share Posted November 2, 2013 have you ruled out predatory hitch hikers or rogue crabs nipping at it? Quote Link to comment Share on other sites More sharing options...
rockstarwiggle Posted November 2, 2013 Share Posted November 2, 2013 For what its worth my duncan started to die off and then boom after repositioning it to another spot it started to grow back. Now it is back and better than ever!!! Quote Link to comment Share on other sites More sharing options...
boricuareefer Posted November 2, 2013 Author Share Posted November 2, 2013 have you ruled out predatory hitch hikers or rogue crabs nipping at it? I guess that is possible but have not seen any evidence of that being the case. Quote Link to comment Share on other sites More sharing options...

Now it is back and better than ever!!! Thanks for giving me a little hope. So, I ended up brushing the algae off and repositioning it. Lets see if I have the same luck as you.
