Weird white gunk growing in tank?

[Cole_Voeller]

This came on a ball of chaeto. Has spread to multiple rocks, and even grows underneath the sand bed. It’s just kind of an eyesore. Anybody know what this is?

Gotta be sponges

Definitely sponges. Sorry for your loss. That type gets UGLY when they spread. Best way I've seen to get rid of sponges is scraping them off and then covering the area with aptasia-x or some sort of aptasia killer. luckily I have a pink variety that doesn't look as bad, nor spread as fast, but that's how I've been able to get rid of it. Hope this helps <3.

Oh yikes. Okay I will try that. Thank you!

I’ve been looking online at some other things people have said regarding sponges. The sponges are growing in small patched all over in the tank. For the sponges growing on rock, can I take the rock out of the tank and scrub it in removed tank water or RO water? Or will that not help? There is also some growing in the actual sandbed, and I’m doing my best to turkey baster any of them I see. Is there anything else I can do to stop them?

Another thing I saw was to turn off the pumps completely. My tank is currently fishless and no coral. Is this something I can do?

Sponges are a sign of a healthy tank. They filter your water and are almost never a threat to anything.

Agree 99%.....

There are invasive types of sponges that can smother and kill corals, but what you have is just a run of the mil white non invasive sponge.

Yeah, I get that. It’s just growing everywhere, and it look’s really gross in my opinion. If it was just one spot on a rock I wouldn’t mind, but it grows so dang fast. I’m putting my frags in soon and would much rather not have the sponges growing everywhere for that reason.
