STN is that any way I can stop it.

[Supernova26]

Is that any way I can stop STN? My california blue tort coral started to lose tissue at the base and on the tips. It is slowly taking over the coral . Is that a way to stop this process. I think I raised my calcium to fast (from 390 to 450 over the course of 2 days.) and my Alk dropped from 11 to 9.5. I thought that was safe but I guess not.

ive heard of superglueing over a little healthy tissue can sometimes help but many acro's wont stop when an alk swing sets off the stn.

 

sometimes it does, sometimes its frag and prey..funny hows its usually only one colony that does it ( recently had a valadia mini colony do it, i fragged and saved a large portion of mine)

 

best of luck, if you loose it i do have some along with the king tort.

That calcium/alk swing should not have caused STN, at least it never has for me. Any other changes in light, flow, maybe aggression?

 

I like the frag and prey method. Frag back at least a 1/2" to make sure you get healthy tissue.

[Supernova26]

Cool thanks for the response guys. I will try frag it tonight and see if it makes it.

Had a similar issue on the same coral...had to frag it.

Here is a thread on this issue where most of the various remedies have been discussed.

I found that I had let my alk drop to low and once I brought it up, my STN stopped.

Frag and pray. Also, if you have time, take some water to a LFS and get a second opinion on your water chemistry test. My ora blue tort STN'd when my alk was lower than I thought.

Hmm I have salifert alk test kit. It's about 9 months old. Salifert kits are usually pretty good but I will double check with the calibration solution.

Rak,

 

I could bring over my Hanna test kit to check it out. I have found that the new Hanna Alk test kit is spot on if used properly.

Thanks Bruce, I would really appreciate it. I could use it to double check my test kit.

I love the quick accuracy of the hanna alk checker, and not having to go one drop at a time when I am close to the reading. I have been dialing in my two part after finding my alk had dropped to less than 7.5 (was at 9), and the hanna checker makes it so easy. I have been testing everyday for the past week.

[Supernova26]

Well, things are going downhill and I can't do anything to stop it. Pretty much 90% of my sps are showing signs of STN. Thanks to Bruce I verified today that my Alkalinity has been fairly stable at 9.6 . There is nothing more that I can do at this point other than dip every single coral in revive and hope for the best. Any suggestions would be appreciate it.

[Coral Hind]

Sorry to hear the bad news. I would suggest you frag the corals and give some to a fellow reefer to try to save them.

[Der ABT]

aw geez man sorry to hear, start checking things

electricity (if you dont have a grounding probe get one) from heaters, pumps, etc

look for anything that could have fallen in the tank (i had a AA battery kill almost all my sps) mine happened really quick but if there is a penny or anything like that somehting suprisingly small can affect it.

 

....wish i had an anwser let me know if i can help at all, i have a holding tub thats 100g and a 30b breeder you would be welcome to borry for a little while, (has a stand and i have some lights we could rig up if needs be)

 

just let me know, im around most of the day tomorrow

[CaptainRon]

No suggestions other than frag into good tissue and hope for the best as others have suggested. I made a bunch of frags out of some old ceramic tile that you're welcome too. I also have a bottle go glue ready to go! Let me know if you want some help fragging - I can be available sometime tomorrow if you decide to go for it.

Man my ground probe was out of the water. I wonder if that was what was causing it. I am glad you said something. I would have never checked it.

[treesprite]

Not having a ground probe in the tank wouldn't do it. I once knocked a light fixture into my refugium and had no ground probe - I got electrocuted, but nothing at all in my tank showed adverse symptoms.

I think I figured it out what killed my sps. I had a leak at my faucet upstairs and it was going thru the basement ceiling and dripping in the very left corner of my sump. It was a very very slow leak so I never noticed while I was working on the sump. I figured it out when a drop hit my hand as I was doing a water change. I can't believe my luck. In all the places that could have dripped it chose my sump. I building a canopy over my sump now. Loosing corals like that was super frustrating.

At least it wasnt a toilet

I don't see how a very very slow leak could have killed your corals. At the very worst, it would just be a small amount of fresh tap water entering the tank similar to a top-off. Was the salinity affected?
