Urgent -LPS release white thing from mouth

[vincent3oo]

Hello . i did water change yesterday. And i found all LPS keeps opening mouth from time to time. And release white thing since now. Anyone know what is the problem?

Those are mesenterial filaments, I’ve noticed them out on my corals when they want to fight with other nearby corals

Yep, can happen when a coral gets damaged. I would just monitor the coral and watch if the damage progresses

 

[vincent3oo]

Thanks all, good to know that is mesenterial filaments. Actually i placed two new scoly with some damaged tissue inside and relocated some brain coral. May be that is the reason?
Now all LPS are opening mouth with mesenterial filament, except acan lord. I am very worry about it. Is that normal? What should i do now?

 

[vincent3oo]

All LPS has same status, has changed 20% water today.

Could just be a combo of all the changes going on such as the movement and water change. Damaged corals seem to put out their mesenterial filaments as well as when the new water during a water change doesn’t quite match the parameters of your existing water. I’d just give them time to settle in, they might look better overnight. As long as they don’t have gaping mouths or rotting flesh, it should be okay.

Check all water parameters. I would guess your alkalinity is low or magnesium is low. Corals look stressed. Check all water parameters.

Now the disk is dead and the rest coral are dying.
Four fish are ok. Anyone have hints?

Parameter
Salinity 1.023
Alkalinity 11 , one week ago is 8
PH 8.2
Temp 25c
No3 25
Po4 0.25
Mg/ca ......not quite sure as i just bought colombo tester . Cant find Salifert. Why not sure, because it turned to blue color after i added about 1.5ml. But it is supposed to turn blue within 1ml. So dont know if the tester is not accurate or my mg is over 1500...

I’d look at salinity being a bit low and a decent alk swing. Either might be the issue. Phosphates are pretty high but I’m not sure that would cause this

 

[scobeyra]

That's a large alkalinity swing in one week. I'd guess that's the problem. I had a doser malfunction and my alkalinity dropped, then raised suddenly when I fixed it. Lost quite a few corals. I would start checking alk every other day until you get it stable for a few weeks. Don't let it raise or drop anymore.

 

[vincent3oo]

I am now thinking to isolate corals to a 20L bucket for a night with new water. Is that good? Or just keep existing status and wait? If Alk is high, how can i make it low?

 

[vincent3oo]

It releases a lot of filament, is it going to die?

 

[MrObscura]

Your salinity is low and more worrying your Alk is all over the place.

is it possible you contaminated the tank with some kind of chemical? On your hands when you did a water change? Do you run carbon? If not, I would just in case.

If everything was fine then something is wrong with your water change. The water change water parameters were not good or contamination. Or the salt mix parameters are drastically different then your tank water.
