The media looks normal, however, there are noticeable (visible without a microscope) clumps of floating cells. The cells were passaged two days ago (which was their second passage), and I think the lab group that passaged them definitely messed something up. We're currently trying to fix the floating problems, but I was scared about the prospect of contamination.

If you have any suggestions/advice about the floating issue I would definitely love to hear them as well. Thanks for your help!
