+1 with meegosh. Any particles in the water column would be caught in poly-fill. By chance how often do you change the polyfill? I change mine every two weeks and it's amazing how FILTHY
they can get in two weeks.
Are these particles only floating on the surface? If so are you running an air-stone?
Could be micro-bubbles that look the particles, especially when you look at it from below the water line with the lights on. I have something similar and I know it's just micro-bubbles.
