Can be a couple of things, especially if this is a new tank. Sometimes sponges grow all over the place consuming excess nutrients; sometimes is calcium carbonate precipitating out of the saltwater. Have you tried cleaning it off? Is it soft and easily squished or is it gritty?

Not at all, but if they’re annoying you can just scrape them off.

No - just appears in numbers. I do scrape them off but into a net and reverse net in toilet to totally rid of them otherwise they just plant themselves elsewhere

 

[paulydee67]

they sound like a pain.
