Hammer coral died THEN a white film took over the skeleton...what is this stuff?

[Kan9]

It was crazy because it happened in 24-48 hours after the polyps disappeared. Will this hurt my other euphilia corals near by? What is this stuff?

Looks like sponge of sorts. I have something similar that grows on rock that's shaded in a low flow area.

Maybe-it went from nothing to what you see in 48 hours, maybe less. crazy?! I do have high silicates though so....?

I'm honestly not sure. I'm no expert. I honestly don't even consider myself a novice, I'm below that, lol. It could be something bacterial even. Maybe reefsquad might know. I know my sponges grow fast in certain areas but they don't go beyond their little home they found. Just low light/low flow.

Well thanks for the response. Par at this location is about 120 so maybe a little high for nonphotosynthetic sponges...

Anyone else?

I'll bump a little help #reefsquad

Lightning fast response. The reason I love this place.

Bacteria.

OK-THANK YOU! -is it normal? Should I remove it (will it effect the healthy coral nearby)?

 

[Jeeperz]

Pull it, imo. Don't want the bacteria to spread to those other nice corals and potentially harm them. But another opinion may be better than mine.
