Hi Reef Community,

I need some help identifying an unknown light green slimy looking thing popping up all over my live rocks. It doesn't really look like a type of algae or a critter. I first noticed it a few months back but ignored it because I didn't think it would be a big deal. Now I'm starting to see it pop up everywhere on my live rock. Please help!

I see some sponges and a wiry turf algae. Sponges are good for your tank, providing living filtration. I'd remove any that encroaches on valued corals, etcetera, but otherwise its good!
