Nicole, I have the EXACT same thing. We vacuumed last night and it all came up fine (although I think it just disintegrated into a puff which made me think I vacuumed it), but this morning it is back!!!!! Not as heavy as last night, but it's back for sure. I am going out right now to take a picture of it. You can see it clearly because my water is so clear it's like liquid glass. I'll report back with the picture in 10 minutes!
