Are my Corals Bleaching?

[Sento]

Hey !
I got a tiny question about my corals like are they bleaching? Or did my Sexy shrimp just eat all their polyps they do not look healthy at all imo any idea if its that or a flow problem or a light problem? The water parameters are fine so I dont know what is happening

Sorry to tell you, but those are very bleached corals.

 

[Mr. Mojo Rising]

They look completely white, either bleached or dead

 

[Notsolostfish]

100% dead. You stated water parameters are fine. But what’s the actual numbers. What par those corals were getting? How old/new the tank is. All this stuff matters to figure it out

 

[Sento]

The only coral that still has polyps is the acropora in the middle is it somehow saveable?

What was the fault ? Where they too low in the tank? Or did the Sexies mess them up?

 

[voelter76]

They look totally dead to me as well. Pics are just blurry enough that I can’t tell if there are any polyps left.

How old is the tank?

 

[Jasonak]

They are dead.

alk of 7 is lower than most, should be around 8~9, especially for acro's. Nitrate and phosphate is very low. 3 months old tank is still new for acro's. What type of lighting and flow in the tank? Have you kept corals before, acro's are the hardest corals.

 

[voelter76]

As Mr. Mojo Rising pointed out the Alk is too low in my experience. At 3 months hs the tank looks pretty sterile.

 

[Borat]

Your corals simply hid - until the times that your tank is mature and ready. So you should wait for these corals to reappear.. maybe 3-4 years though.

The light is a Cube40 from aqua medic

Flow was low in the part where i had them

I am keeping in my Older tank
Clavularia, Duncan , Galaxea, Alveopora, Gonipora, palythoa , briareum, kenya tree and toadstool and a handfull of Zoas ,

"Moved them up"... as in closer to the lights?

Usually you'd want to change light environment (or anything that changes in general) slowly... if you moved them from the bottom of the tank to the top they might have bleached from too much light change.

I moved them up like half an hour ago to make a better picture of them and away from the inverts they where at the bottom of the tank before that and looked bleached already

Ah, OK... just wanted to check.

But, as others have said... ALK seems low.

How long were they in this tank before they started looking pale?
