floating particles

[chris c]

Thank you all very much for the input. Its good to know that I am not the only one with this proplem. As far as live stock I have the following in the tank right now.
Yellow tang, Purple tang, orange sholder tang, sohal tang, cramini tang, tomato clown, fire clown, french angel, queen angel, emperor angel, and one sleeper goby.
The particles are not on the surface of the water, but in the water itself. It is not quite a snowstorm of particles, but not just a little either.
I appreciate your help,
Chris
