Please help me to solve corals dying mystery.

[Ali-F]

Hi all,

I need someone who can help me to know what is wrong with my tank.

First I'll start with introducing the tank.

* Tank size = 200x70x70 cm ( 1200ltr).
* Tank age = 22 months
* Following Triton other method
* 2x maxspect fx280 wave makers
* vertex alpha 300 protein skimmer
* ATI powermodule light fixture ( 4x75w led & 8x80w T5)
* Apex neptune classic with 2 dosers pumps
* Emperor Aquatics E50S-230 UV Sterilizer

Most of my coral frags are dying after some time. Both SPS and LPS. They do good at first and show some growth (extended polyps and encrusting). I am keeping all corals at their best place considering light intensity and flow. But then with no clear reason corals start dying.

I am starting with easy level corals such as monties and acros but also these dyes after some time. The only corals growing like weed is the GSP and some mushroom. I have also a torch frag doing okay for the time being.

As I am following triton other method, I do ICP test and results show good water chemistry!! Here is the last test I did early this month.

Triton Lab Showroom - Explore this water test results and click on the image above.

Someone wants to show you the water test results and shared this link to the evaluation. Click on the image above to explore the water test results.

Also kH is stable at 7.5

I feel depressed as I invested so much building the tank hoping the problem will be solved but it isn't. I don't know what can I do more!!

Please, I need help.

I am not sure if this thread is placed correctly or it should be in another section.

Other parameters?

Other parameters?

Yes, N03?

How old is your system? What's your source water? Light intensity/Par?

Please provide a picture of your tank.

I think the OP answered at least two of those questions in their list of info.

Sorry, don't see that, respectfully.

Other parameters?

*Water temp is between 24.8 - 25.3
*pH is between 7.8 - 8.1

Also I have shared the triton ICP test result for detailed water chemistry. Pls let me know if the link is not working.

* No3 is zero or below detection limits.
* water supply is through RODI filter.

I know this is going to sound weird, but have you checked for stray voltage? Might be something to look into...

The triton tests shows a few elements out of order. Iodine is low, reads 0. Ba is a little high. Also Aluminum slightly high.
The iodine I would certainly slowly increase with supplement or a salt mix in which you know had in it already.
May I ask which salt brand you use? Rodi water? Make yourself? Buy from lfs?

 

[ReefRondo]

Coraline sure is happy!

I see low PO4 and you said undetectable NO3. This is very dangerous and could be the very reason why your corals are dying.

I agree. It sounds like the corals are starving, which is why they do well at first but then slowly deteriorate.

I followed the recommendations/ corrective actions and dosed iodine, Boron, Bromine, Potassium, sulphate, lithium, and molybdenum accordingly. This was done last week.

I am using Red Sea Salt mixed with RODI water.

I am dosing Red Sea Reef Energy A & B twice a week. ( stopped it since two weeks as most corals died)

I also sometimes i am shutting down the skimmer to allow No3 accumulation.

Any media reactors?

 

[Ed Hutchings]

Water is too clean. Also in the pics it doesn't really look that bright. Are you running mostly actinic T5 bulbs? By wattage you should have enough light (depending on height off the surface) if you have the right mix of bulbs but it just doesn't look very bright in any of the pics.

Any media reactors?

Yes, rowa phos and rowa carbon
