Weird white spots/shells/eggs??? - not what you’d think

[Kactai]

These 1/8 inch pure white shells/spots have been appearing in my reef for some time now. They typically disappear after a few weeks. They are on the glass, on rocks, on frag plugs, wherever. Never on actual corals or skeleton though.




Any ideas?

You got it. Shocked I’ve never seen them before. 15 year in the hobby and still learning almost every day! Thank you!
