Hey Joel, when you say the water was full of tiny specs you mean these larvae are pelagic?

That was my conclusion, yes, that they are a pelagic/planktonic larvae. The water is filled with them at a rather high density. They look almost like rotifers in size, maybe slightly larger. I didn't notice anything in the water prior to the hatch. I wish I had a microscope. This morning the egg string is completely disintegrated and just barely distinguishable.
