Air Bubbles On My Gravel

I'm using a pretty small-grained black gravel in a new tank, and for some reason, air bubbles keep clinging to the grains. They've coated the surface of the substrate like small round gems. I've tried stirring the gravel up to get rid of them, but as soon as a few float up, more materialize in their place.

Any ideas why?

Don't worry - that always happens when you first setup a tank. They will go away in a few days .

Did you use any type of water conditioner or chlorine remover when you added the gravel?

I've had various types of gravel float and get air bubbles before many years ago from pouring water over dry, unrinced gravel, but I don't have any other explanation.

I added dechlorinated water after adding the gravel.
