Strange settled solids result. Anyone ever see this or know whats causing it?

Leaving a sample on the counter it is warming and it can lead to some of the sludge floating after a while. also An increased development of filamentous microorganisms causes two extremely undesirable phenomena: - Bulking sludge - Floating sludge Those are the reason I can see but there can be others. What are the issues with your clarifier? Do you have floating sludge?
I'm guessing this was from the temperature then. Thanks! The clarifier wasn't settling right, blanket was weak and watery. Chemicals have been changed significantly and we found one of our drain vales wasn't seating correctly so that has helped things.
Possible change in temperature caused gases to expand and displacement went from negative to positive. Grab two samples and keep one in a cold water bath and put the other on the counter. What are the issues with the clarifier?
Denitrification can cause floating solids, as they rise with the nitrogen bubbles
