Noticed this growing in the sump.. Any idea what it is?? Not growing in the tank,just the sump..

It's hard to tell with that pic. Is there only one?

 

[boardryder]

I have something that looks similar. I also have a ton of those small white sponges. Might be something similar. Looking forward to finding out what it is too.

It's not the only one.. I have a few smaller growths too. It's hard to get a good shot of it
