Not so new to the hobby but this is something new for my reefing career.. any info would be helpful. Its whitish grey maybe sponge maybe something else idk. The tank has been running about 5 months under sps conditions. I have had a large pineapple sponge outbreak in the last 2 months.
Thanks in advance

I thought I had a pic loaded. But it keeps failing so I doubt this post will get very far...
Apologies
