Hog Head Posted November 24, 2009 Share Posted November 24, 2009 I have two pieces of Acro and the smaller one is melting away from the top to the bottom leaving the white skeleton behind. I checked all levels and everything is within spec or perfect. Nothing has changed except I had to sub a K4 for a K1. The larger Acro seems to like the extra flow. The polyps on the smaller piece where withdrawn before the addition of the K4 and had previously been growing well. Any ideas? Quote Link to comment Share on other sites More sharing options...
jgf86123 Posted November 24, 2009 Share Posted November 24, 2009 hog, have you been feeding them good? that might be part of the problem, and it might also be lack of proper lighting as well. do you happen to have any pics of the acros? it might be easier to diagnose the problem with pictures Quote Link to comment Share on other sites More sharing options...

The bulbs are fresh, only about 2 1/2 months old. Here is a pic from before. The piece in question is in the front and has grown since the pic was taken.

CCR Posted November 24, 2009 Share Posted November 24, 2009 If nothing has changed except flow, then move it. Quote Link to comment Share on other sites More sharing options...
jgf86123 Posted November 24, 2009 Share Posted November 24, 2009 aye, and you may want to look into upgrading to T5HO lighting, everyone i have ever talked to claims that PC, no matter how many watts, just arent enough for acros Quote Link to comment Share on other sites More sharing options...
Hog Head Posted November 24, 2009 Author Share Posted November 24, 2009 The larger piece in the back has grown quite a bit and currently has full polyp extension, seems like even more with the extra flow. None of the flow is directed at them. Both K's are pointed at the front of the tank. I hop they haven't been starved. It's hard enough just to get my wife to feed the fish when I am gone.

jgf86123 Posted November 24, 2009 Share Posted November 24, 2009 it could be RTN, or maybe STN, and i honestly have no clue on how to counter it if it is that Quote Link to comment Share on other sites More sharing options...

Hog Head Posted November 24, 2009 Author Share Posted November 24, 2009 from what i understand' date=' yes, rabid tissue necrosis and slow tissue necrosis only bothers SPS corals[/quote'] Makes me feel a little better. The pieces of Acro were free but I still don't want to see them die off. I just fed the tank Phyto and Oyster feast. Now I am off to try to redirect the K4 a little. Will the sick piece infect the healthy one? Should I remove the sick one? Quote Link to comment Share on other sites More sharing options...
jgf86123 Posted November 24, 2009 Share Posted November 24, 2009 from what i understand, and understand, im no expert here, i dont think its really contagious, if you have lugols, you can give it a dip, that might help, certainly wouldnt hurt any, and if you can get your hands on it, give rods coral food a try, its phyto and oyster eggs in it, along with a ton of other stuff that corals love. its a lil more of a complete food for the corals, and pricewise, it really isnt that bad.

jgf86123 Posted November 24, 2009 Share Posted November 24, 2009 lugols is an iodine dip for corals, its awesome, its a definite must have for adding new corals to a tank, it will get rid of any and all unwanted hitchhikers that are latched onto your frags, check out CA2OR's thread about zoas, its a must read Quote Link to comment Share on other sites More sharing options...

Byrd Posted November 24, 2009 Share Posted November 24, 2009 I had what looks like is happening to your acros happen to me twice. The first time I watched it die away, the second time I ended up taking my dremmel and cutting it just above where its receding. I glued the fresh frag into my tank and all has bee well. I believe RTN was what it was-not sure but I figured cutting away the dead area was better than watching it melt away again. Its been 2 weeks and no sign of whatever it was. I now have 3 frags instead of one larger one but they seem to be doing fine. Quote Link to comment Share on other sites More sharing options...

Hoss Posted November 24, 2009 Share Posted November 24, 2009 If you subbed a k4 for a k1 then I bet that is a big part of your problem. That's a huge difference in flow. If you had an existing water quality issue then the lack of flow is likely exacerbating it. Quote Link to comment Share on other sites More sharing options...
Byrd Posted November 24, 2009 Share Posted November 24, 2009 Can the white areas flesh back out with new polyps or are they gone forever? The white areas never came back. Mine was not an issue of flow either, so what others are suggesting did not apply in my situation. It just showed after a week or so, both times they were new corals, and both corals (actually 3 now that I think about it-2 melted away, I dremmeled the last one) came from the same store in town.

Hog Head Posted November 25, 2009 Author Share Posted November 25, 2009 The last of the small piece died off today and I removed it. All else seems ok. Quote Link to comment Share on other sites More sharing options...
