Spongelike thing growing like crazy killing Euphyllia

[sbroberts]

I have this stuff all over one rock where my euphyllia is. It’s growing up the branches and eventually the coral dies off. I took a torch out and cleaned this stuff off. It’s really slimy and hard to remove. Any ideas on getting rid of it. Might have to remove and replace rock, but it’s decent size and is the base for one section of tank. Not the greatest picture. Everything else is doing great in tank.

maybe try siphoning it out with a water change, use a tooth brush to scrub it off the rock while holding the siphon hose close to the area to catch the debris might work.
