It's a heavy load of organics. If you don't have a surface skimmer/overflow organics will buildup on the surface preventing good gas exchange and light penetration. Having better flow in the surface will help but not eliminate this problem. I recommend you get a surface skimmer or place the feed pump for the skimmer closer to the surface.
