I have been trying to figure out why several of my different colonies are receeding? So far I have a trumpet, two candy canes, several acan lords and micros that are showing the problem, It also looks like my frogspawn is also doing it. what is happening is the tissue slowly receeds toward the mouth till it totally wipes out the polyp, it isnt a quick process, it takes several weeks and can be hard to notice till you notice more and more white skeloten. on the acans and micros it starts at the outer rim of the colony and works its way in. Im kinda baffled right now, Ive tried more frequent water changes, and all my parameters seem to be in check. The only real changes ive made to my system latley is a Geo Kalk Reactor, I only stir it once a day so I really dont see any changes from it. I have always struggled with calcium and Alk being up but have never had recession before, Just hoping this rings a bell with someone. thanks

normally means they are dying. What are your water perameters?
Ya Ive been in the hobby for 12 years. I know what it means when corals are dieing. this is a technical question looking for potential diseases or preditor situations. Ive had most of these corals for over three years. Im looking for someone who may have had the same problem

I've had that problem before. Don't know why. Alot of other corals are thriving in my tank. I haven't changed anything. Haven't moved them, changed lighting, water, feeding.
It makes me crazy.

My micros or acans I've had to cut off the dying part and save what I can.
My watermelon is currently doing it. It was fine for almost a year. Other echino's are doing great in my tank. Suddenly my watermelon started to die. Sad part is the frag is so small that how am I to cut it? $200 down the drain.

ya it really sucks man, Im like you, most everything is doing great in the tank, even the colonies that are receeding look good, they are puffy and healthy till the recession gets to them. its weird? If it was only one coral I would just say it had a problem or just let it go. but I have probly 10 colonies in my tank that are doing it, and most of them are my large acan lord and micro colonies. it sucks!

I've had some success with using Tropic Marin Pro Coral Cure. Once the piece fully healed. One it basically stopped it from advancing. Another piece didn't do anything.

I've recently had success with reef dips as well. When I saw some pieces starting to show signs of recession lately (acan enchinata and a chalice), I resourted to the dipping. It stopped the recession where it was at, and the corals have rebounded nicely. If it's some form of bacterial infection, that may be your answer.
ironman and all delight, hope your corals are doing better. Did the dips work?
I wonder why your corals would start receeding when it seems like all your parameters are ok. If its bacteria, why didn't they recede years ago?
Do you think the corals are receeding because of starvation? Acans, chalices, and many lps can eat food, maybe if you haven't fed them, they were slowly starving and they show that through tissue recession?

I have heard of starvation causeing recession before, But I feed religiously. And I have probly 30 different acan colonies, but only a few show problems, I have tried Tropic marin pro coral cure on one of the colonies, I havent had enough time to see if it helped yet. Ill let yall know. I guess I was hoping for a miricle answer! 
Ironman this is no help but I feel your pain. I keep my parameters spot on, do weekly water changes, etc and from time to time have lost LPS corals for no apparent reason. A couple of months back I lost an Indo Lord colony of about 50 polyps that I have had for over a year. All my other Indo / Non Indo were not affected at all. Last week I lost a 50 or so head colony of candy cane and everything else in the tank looks fine. Go figure.
ironman, so starvation is not the thing with you because you mention you feed a good amount.
nitrates and phosphates are in check too right? I know high nitrates can cause tissue sloughing/recession in sun corals and thought maybe it could happen to your acans?
If you keep your nitrates and phosphates in check, then who knows what happened and you will have to let us know how the coral dip went.

mikekman, hey man, my nitrates are -0- phosphates are undetectable, but as ive been told standard kits dont read it as accuratly as they should? anyway the phosphates shouldnt be a problem.
The coral dip seems to have helped as of today, but it is such a slow process I will have to wait awhile to see if it is the answer.
I have been trying to figure out what could be causeing this, The only water peramiters that I have trouble with is Alk. and calcium. I have added a Geo kalk reactor and it caused a growth spurt in my acros. but since I added the kalk reactor my Ph fluctuates alot more than normal. it used to stay at about 8.1 at night and rise to 8.3 during the day. now it gets to 8.1 at night and 8.5 during the day. and my alk stays low at about 2 -2.5 meg/l, it doesnt seem to matter what I do i cant raise the alk. the calcium also shows low, but I suspect my test kit is wrong, but normally I have a hard time getting it over 400. So I have started purchasing the equipment to start a calcium reactor, I just got the Geo 618. Im hoping this will stabilize my PH, ALK, And calcium. I dont know if this is the problem, but you gotta start somewhere right. thanks for all the responses guys. keep em comming, maybe we will figure this out.

I don't know. Interesting though.

The tissue recession I experience happens fairly quickly. I've had a piece of micros, 30 polyps or so, die in less then 2 weeks. I was basically losing half a polyp per row of polyps daily. That piece I didn't try to dip until it only had about 5 polyps left.
The ones where I noticed it happening early on, I dipped and the recession slowly greatly or completely. One piece I dipped again after a week. It seemed like it was still progressing slowly, so I dipped again. There are parts where the polyps regenerated. So thats a good sign.
I've heard that if it happens to chalices you should check your mag levels. Mine was actually kinda low.
Also stronium is another trace element that I've heard could be low. But geez have you ever tried testing for stontium? Its kinda scary when your read the precautions.
