Orange/tan sponge came in on a frag. Has spread to many spots in the tank.
It starts on frag plug and grows up and over the frag, smothering the coral and killing it.
Have tried:
1. Removing frag and let sit in air for 20 min. No effect.
2. Pouring non diluted hydrogen peroxide directly sponge. No effect.
3. Pouring fresh water directly on sponge. No effect.
4. "Peeling" off w tweezers. Does not peel off rock/frag. Breaks up easily - basically turns to dust when you touch it. Then grows back immediately.
Have about $6k worth of corals in this QT - don't want more to die.
Please help.
Pic of sponge currently killing Utter Chaos frag. Polyps have not opened in a week. This particular frag i dumped H202, ran fresh water on it, let it sit out of water, scrubbed it off with tooth brush. Two days later this is what it looks like.
