No idea what these are

Hi.

These recently appeared in my sump. They’ve been stationary but I cannot figure out what they are for the life of me. They’re a clear/whitish color. Any ideas?

Might be some kind of sponge

Sponges, I've got them in my sump as well. Harmless filter feeders, just keep an eye on them that they don't clog up your return pump

You think? They weren’t there one day and appeared overnight. I haven’t tried to touch them to see what they feel like lol.

It does look like some type of sponge but I'm not sure honestly.
