acan disease? need help

[andrewkw]

I'm sadly having some trouble with my acans. One I bought about a month ago did quite poorly it was about 12 polyps and all but 3 melted away. This happened over a couple of days. I had 2 other colonies right beside it and they were unaffected. I took what was left of the sick acan and put it in another tank. Now I am having some polyps melt away on other pieces this is really upsetting because they were all growing great and they all cost lots of $$$

I don't know what to do. I've diped them in seachem reef dip. I'm gonig to test my paramaters now but I'm almost certain 0 ammonia 0 nitrate.

I recently did have a caclium drop that effected some SPS but the LPS were all fine and the calcium has since been stablized. I'm really worried about a tank crash or at least an acan crash since they are the most important items in my tank.

Hate to hear that. Hope it is not the case with all from Aussie

I had 3 that came in that did not look good (water was freezin) 1 is almost gone and the other two are hanging in there.

 

[andrewkw]

these guys were perfect in the shop and came into my tank perfect. The one that melted away took place fast but as I said i had 2 other colonies litterly an inch away and neither had signs of whatever it was. Now 2 weeks later one is showing signs and the other which is my most established is still fine. 2 other new ones I got are not looking good. Other acans look good.

I'm really scared this tank is 1year old and has never had problems like this...

Did the Acans turned white or have a white ring around it's mouth??? I had one Acan do that on me and melted away but all my other Acans were unaffected. The one that melted is actually making a comeback now. Don't know why it started to melt.

May want to check your magnesium level also. Acans can start polyp bailout with low magnesium level.

Its funny that this thread came up, as I have lost most polyps on 1 of my acans as well. It is my first loss in many years, and the first time I have lost an LPS (SPS is another story). All other acans and micros are fine. I blamed it on a clown goby, as he perched there a lot, I thought he was nipping at it when I wasn't looking. As for magnesium, I am a routine tester/adder so that is not a concern in my case. Good to know though.

I've had the same problem with this also.They came in great,then weeks later they bail out?This also has happened to Enchinos also.And tio this day,haven't been able to figure out why I want to add these LPS corals,but not if they die off.I've gave them more light,less light.And flow pattern also.But the results have always been the same.I've had them in my wifes sand bed tank,do the same thing.And even moved the to my BB SPS tank with low nutrients,and the results have always been the same?Till this day,I can't figure this one out at all.Yet SPS is harder to keep and running,compared to the LPS corals.But these certain LPS corals are getting the best of me?They just slowly melt away?Acans,Micro's,Enchinos.Give it to me and I will kill it for sure
Yet all my other corals are growing like weeds.
Yes I would like to know also,what it takes to get these guys grow,than melt away?

Eric that sucks about your pieces...I wanted to come and drool.=(

I have heard a couple people having issues with their newly acquired aussie lords. If it is an infection, I heard it can and will destroy everything if not treated properly and most times you can't get rid of it. I heard also, most lps will get the same infection and echinos the worst (melting, peeling away).

I would check parameters first and make sure everything is dialed in. If everything is good, then do a dip. Monitor the damage and if it still is doing bad, you can frag the healthy part and dip again. Keep it away from the others to prevent spreading and if this doesn't work, then your sump has a very expensive skeleton.

Ciao,
Jen=)

i have to admit i don't test frequently and i was shocked to find i have nitrates in my system 20-30ppm. I have TONS of cheato in my refugiem and since my original cycle a year ago i've never had any. I've moved the sick acans to my 15g which came up with 0 nitrates and nitrite. 0 ammonia as well. Calcium was at 450, phosphates at .5 ii cant find my magnesium test kit but i have one somewhere if i don't find it tonight i will pick up another. my test kits are seachem or salifert,

i think the acans are the source of the nitrate problem as i've been really gun ho about feeding them daily and sometimes twice daily which is probably the source of the nitrates. I have heard aussie corals need spotless water since the water there is a lot cleaner then indo. Ive put carbon in my phosphate reactor and did a 20% water change.

I don't think the nitrate is it but its certainly not helping. Im scared to sleep and wake up to skeletons.

Also i have one of the original aussie acans to make it into north america legally. It's been in canada since march 6th and althoguh i did bleach one piece i have another of the same colony which is thriving and is still looking great in the same tank as ones that are fading.

magnesium is only at 1200. By sheer luck I got some seachem magnesium additive so I will bump it up to 1300-1350.

This has happened to me too. I've lost a few colonies. Mine happened to Micros though.

Same here. The Aussie frags i got from Atlantis are doing well though.

Yeap me as well...a very wise person told me to check & dose Stronium if needed. Since than everything has been fine.

 

[andrewkw]

I have the sick acans contained in a 15g that has 0 ammonia / nitrate / nitrate. I'm raising the magnesium to 1300 its at 1200 now so not too low. I don't have a stronium test kit. I will try and pick one up tomorrow as well as additive. only my aussie acans are effected and not all of them. Indo ones seem fine.

I've lost several acan colonies over the last couple of years while blastos in same tank are fine. What I believe is the problem is they're more susceptible to high nitrates than other corals. Can't prove it, but I've always had high NO3 (20-40ppm) and the acans always carked it first. Beginning with recession around the edges and sometimes with bailouts. Other LPS corals were either unaffected or far less affected. (softies not affected at all)

indo acans are not effected, only aussies.

I lost my favorite colony

and another great frag i just picked up is all but a goner. Meanwhile another one I picked up the same day is doing fine and extending its tenticles.

50% of my great collection has turned into brown slide and skeletons.

 

[andrewkw]

oh didn't see you are from sydney...

man this really sucks.

 

[water hazzard]

Maybe it has to do with the fact that these Aussie acans came from the wild a short time ago. Maybe they are stressed getting used to our systems.
