Cloudy Greenish Tank...What's going on?

[mandyplo]

To try and answer all the questions at once:
Don't know anyone with a UV sterilizer
No not running carbon or Gfo yet (bought some, just need to do the big tank move before I can set up the reactor)
We have no clams and no coral except for 1 little 4polyp zoanthid frag
Only fish are 2 dispar anthias 1 blue chromis 1 kole tang 1 yellow watchman goby
No my bf turned off and back on the skimmer and I can quite confidently count on the fact that he did not clean the cup before turning it back on.
We turned the lights off going to keep them off for a few days and see if anything clears up.

As for tank specifications, tank is just shy of 1 yr old, 55gallon, aragonite fine Sand bed 2-3" deep, 45+ lbs live rock, carbon filter and protein skimmer rated for 200g tank and 2 Hydor 1050gph koralia powerheads
