The ReefBox Posted February 16, 2017 Share Posted February 16, 2017 Need more info about your system and parameters Quote Link to comment Share on other sites More sharing options...
Lexinverts Posted February 16, 2017 Share Posted February 16, 2017 Looks like RTN. Lots of things can cause it. You'll need to report your water parameters. Alk, Ca, Nitrate, Phosphate Quote Link to comment Share on other sites More sharing options...
Vance164 Posted February 16, 2017 Author Share Posted February 16, 2017 Sorry was at school when I posted needed to test water still. Alk: 8.4 Cal: 400 Mag: 1480 Phos: 0.03 Nitrate: 5ppm Salinity: 1.26 Ph: 7.6 75 gallon with about 30 gallon sump. Simplicity 240 skimmer just did a 30 gallon water change parameter were close to the same before water change. No other corals seem to be showing any problems.

The ReefBox Posted February 16, 2017 Share Posted February 16, 2017 Any swings? How do you dose alk etc? Quote Link to comment Share on other sites More sharing options...
Vance164 Posted February 16, 2017 Author Share Posted February 16, 2017 Any swings? How do you dose alk etc?Currently I'm not consuming enough alk cal mag. To be dosing I have dosed baked baking soda to raise alk up a little bit numbers are pretty consistent no substantial changes I test weekly at a minimum.

beer503 Posted February 16, 2017 Share Posted February 16, 2017 Look like you might have red bugs double check it with flash light they should move around. Parameters look ok! Quote Link to comment Share on other sites More sharing options...
Vance164 Posted February 16, 2017 Author Share Posted February 16, 2017 (edited) I will look closely for anything but haven't noticed anythig Edit: I looked really closely didn't notice anything but I will continue to look. Could it be one of my fish? Yellow tang jewel damsel and melarnius wrasse Edited February 16, 2017 by Vance164 Quote Link to comment Share on other sites More sharing options...
xmas_one Posted February 16, 2017 Share Posted February 16, 2017 30g is a pretty big WC for a system that size. If your WC water is not balanced to the alk in your tank (I can tell you that it is not since you are not dosing) you are swinging the heck out of your alk with your WCs. SPS hate alk swings. What salt are you using? If it is something like RSCP that is going to be your problem right there. Quote Link to comment Share on other sites More sharing options...
Vance164 Posted February 16, 2017 Author Share Posted February 16, 2017 I'm using Kent marine salt the alk was at 9.5 a few days before the wc first water change I had done in a month. Which from what I have read for dosing alk 1 point change is an acceptable amount for increasing. Nothing else seems to be mad just this one coral. I'm still pretty new to this I have a little over 100 gallons of volume so I figured 30% wc wouldn't be too big of a deal? I come from an estimated index planted tank so I'm use to doing weekly large water changes so learning this small water change game Quote Link to comment Share on other sites More sharing options...
danlu_gt Posted February 16, 2017 Share Posted February 16, 2017 Has it gotten worse? How are the other SPS? I know a lot of people don't chase pH but 7.6 seems a bit low to me. I'm not saying that's the reason. I know in the winter time, we tend to keep doors/windows closed and oxygen level can drop enough to cause pH in our tanks to drop. To test, you can take a cup of your tank water and place it outside for a bit then test the pH. http://www.reefkeeping.com/issues/2004-09/rhf/ The nearby polyps looks happy so I don't think it's your water parameters. It doesn't look like ALK burn to me since that usually happens at the tips. From my experience with black slug that start at the base and work up, not sure about acro nudi or flatworms. If the frag is easily removed, maybe dip it to see if anything comes off. Quote Link to comment Share on other sites More sharing options...

I will also try and remove it and dip tonight to see if anything comes off. No other corals show any signs Quote Link to comment Share on other sites More sharing options...
Emerald525 Posted February 16, 2017 Share Posted February 16, 2017 I also wonder if there is something nearby that is stinging it. Any other neighboring corals? Do you see any hydroids nearby? The area looks too localized for me to think it is something with your parameters and like you I would expect that other corals would be showing signs. I think dipping is a good idea and just looking around and seeing if there is anything else that could be touching it. 1 Quote Link to comment Share on other sites More sharing options...
fishboys Posted February 16, 2017 Share Posted February 16, 2017 I was very suprised the first time I seen the stingers or sweepers on the chalices and the different soft corals I have. Flashlight your tank and see if anything is stinging it. I think I am just repeating what queen E was saying 1 Quote Link to comment Share on other sites More sharing options...

Lexinverts Posted February 16, 2017 Share Posted February 16, 2017 FYI: Hollywood stunners have some of the longest sweepers that I have seen. 1 Quote Link to comment Share on other sites More sharing options...
Vance164 Posted February 17, 2017 Author Share Posted February 17, 2017 (edited) FYI: Hollywood stunners have some of the longest sweepers that I have seen.I have seen them come out and they are long about 3-4 inches. But there's a coral between this and the Hollywood stunner so I'm going to rule that out Just finished dipping this piece and I saw nothing come off. But I did notice this on my green star polyps you guys have any ideas. Edited February 17, 2017 by Vance164 Quote Link to comment Share on other sites More sharing options...
