Help saving my Favia Coral

[claudio wagner]

Hello folks,

Can anyone help me to save my Favia coral?

Have many other corals in the tank, including euphilias, goniopora (that was no easy to make it happy) and even a few sps with no problem at all.

Following some recomendation I have seen, moved the Favia to low light point. I do not spot feeding any coral at all. Using Zoo Plankton from Seachem once or twice a week in the water tank. Dosing Triton method for about 6 months now.

Any suggestion, please?

I’d would always start with parameters, length of time system running, how many months stable so water chemistry issue can be ruled out.

Full tank shots are also very helpful.

Agree with above. What lighting. What par is it under now? PO4, NO3, stable alk? What corals next to it? Details......

@Tcook @Uncle99

Parameters

Kh 7.5 stable
Ca 400
Mg 1400
No3 0
Temp 25oC

Phosphate I dont measure.

Dont have a par meter but I have a AI16HD

45 cm of water columm. So the PAR at the substrate should around 50-70.

Tank pic as follow

With you NO3 I would be worried about zero PO4. However, the bubble and euphyllia look fine so probably not a starvation issue unless those corals are new additions. How long has the favia been in that location? What's to the right? Bowerbanki or favia. Could there be some stinging at night?

A little tweeking needed. These only require moderate light and water flow. they are susceptible to stinging/being stung by nearby coral. The bubble coral could be a culprit.
Mag a little high, CA a little low.
recommended:
Temp 77-79
ph 8.1-8.3
salinity 1.025
nitrate < .5
phos < .04
Ammonia < .03
mG 1300
Alk 8-10
CA 440

Should be able to take straight bright light in that tank. How longs it been in ur tank? Try and keep ur alk. Ph. And salinity stable. Might recover but looks ruff imo.

+1 on the bubble coral

 

[Uncle99]

Your numbers indicate a very very nutrient poor system with Nitrate at zero....and maintaining appropriate levels of phosphate is critical to corals long term survival.

You gotta manage your N and P, or things will slowly shrink.

The dkh is low IMO, not a lot of room on the lower end.

Thank you folks. Triton method preconizes that KH will stabilize at 7.5 , maybe 8. So, I may try to tweek the dosing higher, but this will take a while ( I may increase 1 ml per day per week and track the results ). nothing fast work well with regards parameters in my opinion.

About how fast recending... Loosing one "mouth" ,if I can say that, per week. I have this coral for 6 months now.

Thanks anyway

Thank you! Yes, other Favia 1 1/2 inch aside. Yes those are blastomussas nearby. Thats the problem with nano tanks... :/ Never see any visible tentacles. Will try to space a bit more though... I have in the other side of the tank galaxeas , those are evils on stinging...

Thanks for your opinion. What ruff stands for? Lol

Rough. Not good. I just spell it shorter sorry.

Been in there for 6 months. Was it ever looking good? Not a very clear picture but that large favia to the right looks quite contracted. Take some water to your LFS and have PO4 checked and confirm other tests.

Low nutrients and too much light spell disaster.
