White center on my colonies

[Oscar Bravo]

Anyone knows why the center of my colonies are getting white?

Looks like a bacterial issue, can you get a clear picture so we can see the coral closer?

The one on the right has been like that for months. Now I notice on my Pink Cadi too. Alk is low, 6. Its hard to keep it up on my tank. I will try to get closer.

I took a few daylights

Im seeing lots of bite marks, AEFW

It would had killed the colonies long ago.

Not exactly, aefw can only really kill colonies off entirely if the problem goes unseen, and they are allowed to reproduce unchecked, that can take months to get that bad.

See those circular "scars" ? =AFEW

dang and it’s so hard to get them off. It’s been months like that.

Better pics will confirm, Id be looking for egg masses on dead skeleton or all along the base, they wont lay eggs on living tissue, they lay eggs where the acros base meets the rock or, in this case on dead skeleton next to living tissue
they can easily be mistaken for algea growth, but if you look very closely you will see the golden brownish-green spheres clustered together, each egg is around the size of a grain of refined sugar, or even smaller.

Wish you the best of luck in your upcoming battle with them.

With diligent weekly dipping, sealing and isolation they can be beat, but its a lot of work.

Looks like AEFW. Its not as much of a death sentence as people like to think it is.
Remove the colonies, place them on disks so you can remove them from the tank and dip weekly. Buy some yellow coris wrasses and start dipping. If you're patient and have time they'll be gone in no time

 

[Oscar Bravo]

That’s what it was. My yellow Coris wrasse die 6mo ago. I had seen this before but it went away when I had all my wrasses.

 

[Oscar Bravo]

Well you

Found some eggs at the bottom the the colonies. I smashed them and killed them with my finger. Some fell to the bottom. Hope they get eaten by other corals. I have a long way to go.

Don’t freak out they arent as bad as a lot of people think. Just baste the corals off to keep the worms from taking hold until you can treat. I had luck with flat worm stop at a double dose which eventually killed them. After a few months you won’t even notice they are there.

By treat you mean dip?

Either treat the tank by dipping all acros once a week for 5 weeks or if your patient then dose a double dose of flatworm stop for 6+months until you can’t find them anymore I have had success with both methods.
