Why are my corals turning brown ?

[Lavey29]

What do I dip it in ?


I don’t know what brown jelly looks like. Can you tell me if that’s what is on my duncan ? If so, I’ll just throw it out.

It's hard for me to tell in the pics. Basically a coral head will rapidly close up and die in 24 to 48 hours and you will visibly see a brown jelly like substance oozing out of the dead head.

I Wouldn't throw it out just yet. It could be just algae on a dead head. But if it looks like brown slime, it could be. I like to use Coral rx dip.

It’s not the corals turning brown, it’s brown algae growing on the skeleton where the tissue has receded/died.

He lives in Canada and I believe it's illegal there for fish medicine.

Coral rx is not illegal in Canada. Fragbox Corals, and many other Canadian retailers sell it.

I took the duncan out of the tank and removed the brown/whitish part. It’s not soft, it’s rather hard. I wonder if it could be sponge since I have been dosing silicate for a while and it is know to cause sponge growth.

But what puzzles me is that there was part of the mystery stuff that was moving with the flow. Something else on top of the sponge ?

I put the duncan in the sand for now but it’s making me nervous because it’s close to other corals.

i'd be generalizing to say this but often its not even a husbandry issue and more of a lack of tank maturity leading to instability. i found things weren't really in my hands completely until about the 18 month mark

what you pulled off of the duncan looks like glue that wasnt stuck to the frag.

That is superglue.

I was hoping to have stability around the 12 months mark but it will probably be longer than that. I made a big mistake that cost me stability (magnesium way too high).

That’s weird. If you look at the video then, what’s swaying with the water movement ?

Maybe BJD on top of it ? Can misapplied superglue kill a coral in the long run ?

The duncan had more brown stuff on it today, and looked pretty much dead. I took it out of the tank and oh my, did it stink ! I’m hoping that’s what’s bothering the other corals. I put carbon in the filter and turned on the UV just in case. I’ll let it run 24-48 hours and keep the carbon going for 1-2 months.

We’ll see if that helps.
