Okay cool, well that helps narrow it down a bit then :-)
My second guess would be something along the lines of a Spirorbis worm. They start as tiny white calcareious specs on surfaces and if they don't die they can appear as tiny spirals. I get these buggers growing in my sump. They're harmless, as far as I can tell. There are other such small calcareous worms that look similar. If you tough them are they hard ? Try pulling one off and seeing if there's a warm under the shell :-)
