floating particles

[chris c]

Hello, I am new to this forum and I have a question. I have a 280 gallon reef tank with 200lbs of live rock and 60 pounds of sand. I am having a major problem with lots of floating particles in my water. I am handling filtration with 2 8 inch filtration socks that are fed by 2000 gallons an hour from my overflow. I have a bubble master 250 skimmer and a 55W UV clarifier. My sump has a large built in refusium with 50lbs of live sand and macro algae. If anybody can help me out with suggestions on how to solve my water clarity problems, it would be much appreciated.
Thanks,
Chris
