Do you run a skimmer?
Have you tried activated charcoal? It works as a water polisher, making it nice and clear.
I purchased a blue spotted kole tang, algae problem is now eliminated, and I have to place algae sheets to feed him, to my delight. My lawnmower blenny tried but the algae was more than he could handle alone.

Hook up a UV Sterlizer or Ozone.

I agree with the carbon; but I like Boyd's Chemi-Pure much better. Are you running any kind of mechanical filter? Sponge, pad, etc.? You sound like you may have particles big enough to remove with that type of filtration. Carbon & Chemi-Pure are chemical filters that remove mostly liquid & gas pollutants. Chemi-Pure will also absorb a lot of other dissolved stuff. BTW, I'd feed a much more varied diet and use a vitamin supplement. There are many frozen foods that are far superior to flakes, with far less waste. If you want to use a dry food on occasion; try pellets instead of the flakes.
