tank crash

[Dustin2]

Looks like my tank is crashing right now. It all started this morning. all my levels are ok. all sps are white. I need some help/advice on what to do Also all corals in tank dont look good

 

[Dustin2]

also forgot to add all fish are fine

 

[Bcollins111900]

have you done anything differently as of late?

 

[Dustin2]

nope nothing to my knowlege also should i be worried about my fish finding them new homes?

here is a link to some pictures also the water is really cloudy

Spawning clam or other invert??

 

[Dustin2]

that was my first guess but all my sps are white would spawning cause them to bleach

 

[oldreefer76]

Are they bleached or lost all there flesh RTN

 

[Dustin2]

i am not really sure it looks more just bleached and it looks like they still have he flesh on them

On rare occasions the Zooanthellae within bleached SPS will recover. It depends on the sensitivity of the specific SPS and what caused the bleaching and was it slow or instant. Slow depressed pH or high within reason, SG or nutrient build can be corrected and some SPS will make it. Along the lines of where I think oldreefer is headed is if you have flesh damaged occuring with bleaching it will pretty much be a done deal.

But the key here is you want to find out what caused it. You want to inspect as many water parameters as you can and go over what you have done to the system in the last 2 to 4 weeks. Did you change over to new bulbs with much higher PAR? Did you put a new reactor online? Is the reactor setup correctly and such? Otherwise you may fall into the same pitfalls again.

The 3 most common suspects for SPS death, other than system failures like power outages or electrical issue that trigger other events, that I note on well maintained setup postings are lighting change, big alk change and or big pH jump. Any of these happening too fast and or too radical will nuke your SPS in short order.

 

[oldreefer76]

What are your current water parameters? I would test immediately

 

[Dustin2]

salinity-1.024
ph is 8
calcium was 400
alk was 8 or 9
Nitrate was around 0

I did have an SPS (small) frag drop into my large 9" clam last evening and it slammed shut quickly. I thought I got all the pieces out last evening as well, but this could have caused the clam to go into a spawn (reactionary mode).

The was numbers are of no help what are they now?

 

[Dustin2]

Sorry - These are the numbers as of 1 hour ago when last measurements were taking.

OK so you actually went into the calm to get the pieces out?

 

[Dustin2]

no there could possibly still be one in there but i am not sure.

Temp would be helpful too. If you had a temperature spike, it could have bleached the corals quickly...

 

[FishNFun]

If I see anything funny happening in my tank I always like to throw in a poly filter (the good ones that change color) just to make sure. If you're not already doing it, I'd start running some carbon (or refresh it) and do a water change. I've never had RTN but I don't keep a lot of SPS either. From what I understand it's pretty easy to identify and progresses very rapidly. If it is RTN you could try fragging the good areas. Maybe go ahead and set up a holding tank just in case. Good luck!

My vote is either temp spike or drop in alkalinity. I have experienced both with die off.
