Is this brown jelly?

Notsolostfish · Feb 25, 2026

Iv statted this tank 2 years old grew frags to colonies. My parameters always been stable.

Alk:8.6
Cal:460
Mag:1400
Ph:8.3
Nitrate:6ppm
Phosphate:0.16

Every single frag in my tank died this way ever since 2 years ago, is this brown jelly infecting my tank? I dont get it for me it looks like those heads are being shaded and dird thar way, but why are they having the brown goop?

Tank overall doing great my issues always been with hammers, last change i did was adding nitrate to go from 2 to 6ppm i was adding 2ppm neo nitro a day. And now i stopped tank is 150G. Now if you say my tank js packed, and theres flow issue, possibly but i adjusted flow as they grew

Looks like BJD to me. Could be caused my many different things, so its hard to pinpoint exactly what the cause would be.

Yes, it is. Probably because that head is fairly shaded.

What do you guys usually do to care for the coral in a case like this? Me, i turn off flow and suck off the brown jelly so as to get it out of the tank. If i can, i remove the head immediately after. Are our pros on here dipping the colony afterwards?

I am paranoid and usually toss. I do not have a good way to remove heads yet, and since it can easily spread I've taken this sad approach.

Yes, definitely brown jelly. Iodine dips worked wonders for me and I dipped any euphyllia I had in the tank.
