Need help with snail ID, massive outbreak

[MandarinCove]

I have hundreds of these tiny snails everywhere. They keep jamming the pin wheel to my skimmer. I need to find out what they are so I can then figure out a way to get rid of them. Any help is appreciated.

That is a Strombus snail (?Strombus maculatus) They breed in your tank. They deposit eggs on the glass and rock, a bubble with about 5 eggs in it. The eggs hatch and the little snail craw out and start eating. Nice population to have in reef tank. My Harlequin Tusk eliminated them from my reef.
