Corals on the process of dying.








Tank a few minutes ago :



The refugium full of macro



Alk 7 - 7.5 dkh for the last 2 weeks. Phosp yesterday was 0.05 ppm

That's all folks. Tank in survival mode.

Not a pretty site, Daniel..
Hang in there!!
You know what you are doing.. It's going to get better!!!!

 

[markalot]

So sorry this is happening, hang in there!

 

[Darth_Tater]

Oh no, the birdsnests! Strange, those seem to be the SPS that I can't kill. I have noticed on mine that they seem to regrow over the dead skeleton pretty well if you can keep just a chunk of the coral alive. Hope this turns out to be the case for you as well!

 

[Usernam Invalid]

Have any ideas what could be going wrong...hope it gets turned around

 

[markalot]

Sorry to hear things are still going bad. Do you think all of it is related to the Alk spike or something else. Gah, I hate unknowns ... why did I get into this hobby! But yes, at some point it becomes an opportunity to add new corals!

Hey Daniel!
How are things?

Hey Daniel!
How are things?

+1 very interested as well, hate to see mature tanks like this have problems.

Thank you all for your interest !!!!

This is what I found at my return home on Thursday:

STN








All those corals are gone by now

I still left these bird nests:








Lots of burned tips

 

[reefmutt]

Uggggh....
Sorry Daniel.

 

[nemodan]

Uggggh....
Sorry Daniel.

Nothing can be done.

Tank today

 

[nemodan]

Acro with no polyp extension for weeks now and losing color





Previous pictures of the same colony

 

[nemodan]

Acros that are doing well





It was cream and pink some weeks ago.








The 3 SSC are all doing well. Their color were different, but the 3 are changing to a similar color

This is very sad. I think you need to cut frag(s) from every colony to save your sps population.

Have you reduced nutrients very suddenly by flooding carbon/GFO/organic carbon? By not doing anything you will lose the lot I am afraid.

 

[nemodan]

The Red planet never stop growing and the polyp extension was always amazing. He grows over the zoas . Look the base at the picture.

 

[reefmutt]

I'm glad you still have healthy colonies in there. It is very hopeful.
Clearly the weaker/badly affected corals are dying off..
When was your last 'test coral'?

I have my tank now again stable like before I changed to AF probiotic salt.

I do not use GFO. My biology to keep Phosp and Nitrates low is the big refugium and Matrix .

Later I will measure parameters for you guys.

I can tell that Alk has been stable for 2 weeks,at ~ 8 (7.8 - 8.2) dkh. And a week ago PO4 was 0.05 ppm (hanna UL).

I am going to see if I find some aa (acropower) in one if my LFS. Beside that I was not adding anything to my tank before.

This is my hypothesis (brief):

Tank was stable and doing well
Changed to AF Probiotic salt.
Started to have problemd to keep Alk stable.
Have 2 power outages. One was 4 hours, I was out of house. Temp went to 76 F and I have an Alk peak.

Now put these 2 things together: tank that was not stable yet with the new salt, plus the big shock of the electicity lost and corals were affected.


Some days later I started to see corals were not going well. AF tells me that I can not have leftovers of the probiotic salt in my mix brute. And I was leaving from week to week around 30 G . Another probable issue ? .

Then I decided to return the tank to his previous status quo. Another change! !!

Now I am again in Reef Crystals salt, with Alk to historic levels (~ 7.5 - 8 dkh) .

All those changes .....affected the corals.

I am not going to do anything because I do not have time to do anything....unfortunately.

My weekly travel schedules do not allow me to do a daily management of the tank.

3/4 of the corals are still doing OK. I will wait and see how the tank evolve. If I can keep it , I will be happy, but if not, it will be shut-off.

I will keep in my memory and in my pictures the memories of the good times.

But for now I just wait and keep doing my weekly maintenance.

Thank you all !!!!!!!

I really appreciate your comments and suggestions.

Best
Daniel

What do you mean Matt by "test Coral"
