help!

what are all these white flat shelled organisms? all lined up in the back corner of my tank?

They are about 1-2 mm in diameter and congregate in groups in different areas of my reef tank

Pic isn't the best but could be snail eggs..
Could be snails/limpets
Could even be sponges

All harmless/beneficial..

Depends upon the limpet. Keyhole limpets are known to munch on SPS. That being said, that doesn't look particularly like that's what you have. It's hard to tell from the picture, but yours look like snail eggs. Do they move?
