xzeror Posted September 22, 2014 Share Posted September 22, 2014 Some of my frags have been receding to nothing. Colonies that have been with me for months are fine for the moment. Only the frags seem susceptible. Any ideas what could be happening? Actually just noticed my scoly shows some slight signs of receding flesh as well.... HELP I thought it was my alk fluctuations, so I started dosing like two weeks ago. I have alk/ca stable now. Alk ~8 ca ~ 470-480. Are there any pests that I should be looking for? Or is it a problem with my tank? I have a hair algae problem that I am dealing with. My brand new reactor with gfo and carbon is set to go up tomorrow. Any suggestions would be greatly appreciated.

717Tank Posted September 22, 2014 Share Posted September 22, 2014 might just be all the changes in water perameters. Take it slow when changing things, you may have had an alk problem but your corals were use to it, so when you fixed the problems you may have put the corals into shock. Gotta do things gradually Link to comment

Gotta do things gradually The skin was receding before that and that's when I started looking for the cause of it. This is when I discovered that after a water change my alk would go from 7ish and dip down to high 5s, low 6. by the end of the week. So I thought maybe that dip in alk every week was causing it. I'm going to buy a doser soon, manually adding two is getting annoying. Link to comment
clownfitch Posted September 22, 2014 Share Posted September 22, 2014 If you were having success with them but now your having tissue loss and haven't changed lighting or flow through all of it then that would point to water quality and or parasite/ pest issues. Alkalinity fluctuation could be the issue for sure. Have you checked the other parameters like nitrates and phosphates? Do you have any fish in there that may be nipping? A crab or other pest/ parasite (these would be more likely to come out during lights out)? Link to comment

I got rid of my tang who nipped, and I have hair algae. So I'm sure I have phosphates. My carbon and GFO reactor have been running for 1 day now, hopefully this will reduce whatever my phosphates are. I was thinking pests.... Would dipping them be a bad idea and just cause more stress? Or is there a dip that would help? Maybe an iodine dip? or just get some bayer and dip for pests? Came home today and one of my mini colonies seems to be showing more tissue loss :< Link to comment
clownfitch Posted September 24, 2014 Share Posted September 24, 2014 An iodine based dip such as Lugols may help but you need to find the cause. Sounds like it may either be high phosphates or pest/ parasite. Do you have any way of checking your phosphate levels? Link to comment
MikeTR Posted September 24, 2014 Share Posted September 24, 2014 That calc is too high. My other guess is nitrates. Have you tested and what brand kit? Link to comment
Builder Anthony Posted September 26, 2014 Share Posted September 26, 2014 100 percent water change and leave things alone for 4 weeks.check if you have any brown slime on those receding if so remove them and at.I have maybe 10 types of scans and they don't mind a 100 percent change of water.I think u have brown slime in there and its just spreading.if so it will kill anything and everything. Frag your colony and place in new tank.that's real good advice. Link to comment
jservedio Posted September 29, 2014 Share Posted September 29, 2014 So what other corals are around your "acan garden" and are you 100% sure that all of them are the identical species? A single bowerbankii or echinata too close to lords will pulverize them overnight. Other agressive LPS can have sweepers up to more than 6" long that come out of nowhere. I had a merulina next to my acans for 2 years and it never showed any agressiveness - then one night out of the blue destroyed 3 heads of my nicest lord and kept sweepers out for a week. Then, after that episode, hasn't shown sweepers again in over a year. Just because a neighbor up to this point has been friendly, doesn't mean they are always going to play nice. Link to comment

I've seen many tanks crash after doing a 100% water change The only tank I've seen survive a 100% water change had 95% of its live stock die. Do a 20% water change and wait; these corals do not need any more sudden fluctuations in water chemistry. Link to comment
farkwar Posted October 30, 2014 Share Posted October 30, 2014 Dumb question. Are you feeding them? Link to comment

I've seen many tanks crash after doing a 100% water change The only tank I've seen survive a 100% water change had 95% of its live stock die. This is entirely, 100% false - the bacteria that break down ammonia, nitrite, and nitrate live on the rock and substrate, not in the water. The only way to cause a mini-cycle doing a water change of any size is to leave things exposed to air long enough to cause die off (which is on the order of hours) or to stir up nasty amounts of detritus (which you shouldn't have in the first place unless you neglect your tank) and don't remove it after (which is just stupid). I have done 100% water changes on both my tanks many times and both have SPS in them (including my 20g which is almost entirely acros). Additionally, there are some pico keepers on here who only do 100% water changes - care to explain how they can do that for years on end without a cycle if 100% water changes caused cycles?
