don duncan Posted February 5, 2018 Share Posted February 5, 2018 Sad day. Went into work and all my sps are dead. Can’t figure out what happened. Alk 10 calcium 400, temp normal rage. This sucks as I just bought about $500 worth of sps from various people. 1 Quote Link to comment Share on other sites More sharing options...

+BobcatReefer Posted February 5, 2018 Share Posted February 5, 2018 Ouch man. Hate to hear it, but curious to see if you can find the cause. I swear I live in fear of total failure all the time and stories like this only heighten my paranoia. Quote Link to comment Share on other sites More sharing options...
Isaac Posted February 5, 2018 Share Posted February 5, 2018 did someone clean you desk w/ something and the overspray got in it? heater fail? 1 Quote Link to comment Share on other sites More sharing options...
don duncan Posted February 5, 2018 Author Share Posted February 5, 2018 No cleaning accidents. I am going to check salinity today, but it should be fine Quote Link to comment Share on other sites More sharing options...
Isaac Posted February 5, 2018 Share Posted February 5, 2018 did the lights get stuck on? Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted February 5, 2018 Share Posted February 5, 2018 That sucks. Everything RTN'ed Don? Or did they all bleach white?I'll hook you up with another Oregon Tort when you're ready. Don't worry about that piece at least. Quote Link to comment Share on other sites More sharing options...
Gig 'em @ NDstructible Posted February 5, 2018 Share Posted February 5, 2018 Aw man, that stinks big time. Just bare skeleton left? Did you dip the corals this weekend with anything? Quote Link to comment Share on other sites More sharing options...
don duncan Posted February 5, 2018 Author Share Posted February 5, 2018 The tort is holding on. No dips, salinity is 1.026. They are just white skeletons left. I am bummed. 3 pieces are holding on. I lost my favorite piece the strawberry short cake. It was doing great. Thanks for the offer Ty 1 Quote Link to comment Share on other sites More sharing options...

You're no stranger to keeping acros so hopefully you'll get to the bottom of it.Were the ones that survived only the newly added ones, like the Oregon Tort?FWIW, my strawberry shortcake is my canary in the tank. It'll rtn first in my tank before anything else if there is a condition not to its liking. If you got yours from Gig'em, then it originated from my colony so probably has the same characteristics still. Quote Link to comment Share on other sites More sharing options...
don duncan Posted February 6, 2018 Author Share Posted February 6, 2018 There was no rhyme or reason to what survived. one millie thats been in the longest survived, Oregon tort, and one other. Strawberry shortcake, pink lemonade, rainbow millie, red dragon, and other various millies all toast. Lights worked fine, no electrical shorts, all parameters seem normal. It's a total mystery.

Timfish Posted February 7, 2018 Share Posted February 7, 2018 What about a temp swing over the weekend? Are you keeping PO4 really low? What are your nitrates at? Were any amino acids dosed last week or over the weekend? If you're using ULNS methods this research shows even though the zooxanthellae provide a higher percentage of the sugers they make to corals for growth it also makes corals much more sensitive to changes in light, temperature and sudden increases in nitrogen. http://www.indiaenvironmentportal.org.in/files/file/Nutrient enrichment.pdf https://www.frontiersin.org/articles/10.3389/fmars.2015.00103/full https://www.sciencedirect.com/science/article/pii/S0025326X17301601?via%3Dihub Quote Link to comment Share on other sites More sharing options...
Neon Reefer Posted February 7, 2018 Share Posted February 7, 2018 I would suspect either metal poisoning or a bacterial infection like vibrio alginolyticus or sphingomonas paucimobilis. You could try an antibiotic dip IE half tablet of chloramphenicol in 2.5 liters of water for 3-4min dip Quote Link to comment Share on other sites More sharing options...
Timfish Posted February 12, 2018 Share Posted February 12, 2018 A bacterial infection certainly could have done this. But as pathogens are found on healthy corals what might have been the stressor to cause a rapid onset of infection? Could a new or different strain have been brought in with one of the new additions? We have solid research showing ULN methods have a negative impact corals immune system and ability to adapt so was there an sudden change in environemntal or nutrient variables? This was in an office so is it possible someone unknowingly did something and there aren't any environemntal or nurtrition issues (I've certainly had problems with "housekeeping" over the decades I've had my maintenance business)?

Kevin S. Posted February 17, 2018 Share Posted February 17, 2018 What about poisoning from leathers? I think you just cut and sold several recently? Sent from my Pixel 2 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Reefpuck Posted February 25, 2018 Share Posted February 25, 2018 Hey sorry to hear about the coral losses. I going to second what Kevin S mentioned above. My buddy/neighbor had a leather that he pulled out of his tank a few weeks ago...and when he did a nearby SPS (strawberry shortcake I think) got some crazy STN and was completely toasted within 12 hours. We checked his parameters (which were fine) and his other sps were fine. We're confident that it was the leather that obviously was irritated when it was removed...that was the culprit. That particular frag was only about 6" from the leather. Anyways...just another thought. Hope you figure it out either way! Quote Link to comment Share on other sites More sharing options...
stoneroller Posted March 4, 2018 Share Posted March 4, 2018 Sorry to hear Don. I've puzzled over similar events (not all SPS but some) in my tank; I'm a lot more careful about what is on my skin (soap, sunscreen, etc.) before I do tank maintenance. Any chance of chemical additions? Quote Link to comment Share on other sites More sharing options...
Timfish Posted October 13, 2018 Share Posted October 13, 2018 Any update on what may have happened? Have you added any new corals and if so how are they doing? Found another paper besides Matz's that shows resistance to bacterial infections varies significantly by genotype within a species. With the increased death from bacterial infections caused by being moved a bacterial infection still seems most likely to me Quote Link to comment Share on other sites More sharing options...
