More issues: SPS diseased?

[oneradtek202]

noticed this nice slimy stuff eating away atn the bottom of my tricolor bali colony today. what is this, how do i get rid of it. is it a flow issue? my stuff has grown up soo much lately that its hard to get flow everywhere. whats going on here?

The other picture is of a RTN that i plucked today. it was a long RTN, capt cully went threw the same thing with this frag. it might be related but i dont think so.

Not sure what the slime is... but it looks like it's also at the base of the coral you lost in the second pic? What will really be hard to determine is if the slime is causing the death or if it's just moving in on freshly vacant skeleton. I've never seen it before so will be watching this thread.

Can't offer any suggestions as I'm still learning but wishing you the best in your battles. Your tank was always awesome. I hope everything pulls thru for you...

thanx guys, im almost on the edge in tearing this down and doing a 29 gallon nano with quality softies. itd def be cheaper! ill suck the slime up with my next water change. maybe its just chemical warfare? people have always warned me about that area in my tank where stuff is so close together. and now they have grown and its becomin apparent

 

[john90009]

the aptasia anemones at the base of the corals arnt helping get them down and killed then check your parameters the one thats rtning looks not so good i wouldnt count on that one but the tri color try getting it alittle more flow and keep the parameters stable.

 

[oneradtek202]

not an aip, its a few tube worms....quality of pic isnt that great.

aweman sorry to hear, is that the rose millie with blue tips, say it isn't so

 

[oneradtek202]

was! lol the only person that has one still now is pascale. i hope he can keep the lineage alive

If I said I knew what the problem is I'd be lying. I'd guess it's some form of stress from in order: alkalinity bounces,PO4, organic carbon buildup,temp swing, localized nightime hypoxia /blocked flow from the heavy growth, alellopathy or a toxin/metal . I'd do a series of 15% water changes ;run fresh gac and polyfilter. The slime may be bacteria or some form of protozoan infection feasting on necrotic tissue and possibly spreading outward.

Are other corals similarly affected?

 

[oneradtek202]

not yet

i run rox carbon and change monthly. i do 15 gallon changes a week., run a octopus skimmer , i dont overfeed. i have an issue getting a good flow to that part of my tank with out blasting it and other corals.

i feel the swings and alk/calc issues have been stressing it out. but other than that, maybe chemical warfare?

 

[tmz]

I have experienced stn and rtn issues after alkalinity swings due to accidental overdosing followed by some precipitation via a calcium reactor once and once with kalk. Sequence doesn't necessarily equal consequence but since I've dropped my alk to very consistent 9.5 dkh, there have been no problems at all for well over a year. My corals are pretty well packed in but not quite as tight as some of yours seem to be. I'm going to frag over the next couple of days. Your post scares me. BTW don't worry about the calcium as long as you keep it at 350ppm plus. 400 plus is better but not necesary. It's th alk that can cause the problems

Organic carbon is sneaky and you can't measure it at least not with any hobby grade equipment and it may in excess upset the coral symbiont bacterial balances. It comes from food,fish/snail /shrimp/bacteria. etc. waste as well as the corals and other photosynthetic organisms as they convert CO2 into sugars. Think coral slime and algae exudate for example.Running rox should help but gac only takes out some organics( ie those with an affinity for adsortion to the gac). Adding some purigen along with the gac could help if organics is an issue since the purigen may attract organics the carbon doesn't and vice versa. Best organic export seems to be a combination of ozone and gac . Ozone breaks up the chains making more of them friendly to gac. Skimming helps too but gac is more effective, in my opinion.

Fragging might help flow. But you're between a rock and a hard place right now. heavy fragging might add stress. Finding a way to add flow could help.

Running some opposite photoperiod refugia with macroalgae should boost nightime O2 levels offsetting hypoxic conditions somewhat.

Blowing out the rock with a turkey baster where you have flow problems should help too.

Consider testing PO4 if you haven't done so in awhile. I'd check NO3 also.

Good luck.

any stressors can help to contribute to this type of malady. With Acropora it's "live fast and die young". Don't ever give up on an Acropora or Montipora because they can grow back from (seemingly) nothing if conditions are optimal.

 

[RandyO]

Looks like you have some black noxious sponge growing at the base of your Acroporas which can be irritating them.

 

[oneradtek202]

whatever is happening, its happening quickly. i have a water cahnge in the buckets mixing. im gonna suck that crap off tomorrow or thurs.

 

[tmz]

Some polyfilter might help if there is/are toxins from the die off or otherwise.

tossing this out there:

tossing this out there:

use a flashlight at night and look for Asterina on the SPS

 

[oneradtek202]

will do, its weird because i noticed that circular necrosis more higher up on the colony awhile ago but it stayed smalll forever. never changed. there was this stick lookin thing coming out of it too. maybe some parasite? no other colonies seem affected

Stop farting around on RC and go get my chest xray fella!!!!!

did the guy live?
