They are most likely amphipods/copepods, they are a good thing.

Are they moving?

I bet they're hydroids. DO they look like this?:

If so , I had this problem as well. I had TONS of these things when I first got my tank going.

They should all eventually die off. It happened to me as well as others who have had this problem.

I stll have very few but I hardly notics them now.

If they don't move, and they seem like little dots of white "plaster" or spalshes of paint, they might be snail babies :) Assuming you have snails to start with of couse.

One way to be sure is to look very closely. If they are actually a tiny spiral, then they probably are babies.
