Eheim Skim 350 Surface Skimmer
The surface skimmer planted keepers reach for most. The Eheim Skim 350 is a compact 5 watt self-contained unit that sits in the tank and pulls the biofilm off the surface, clearing that oily film that dulls a planted tank and hampers gas exchange. It works in fresh or salt water, installs in minutes, and is the forum favorite for keeping an aquascape's surface spotless. Simple, effective, and cheap, it is the easy first pick for biofilm.

Representative image.A surface skimmer pulls the oily biofilm off the top of a planted tank so gas exchange improves and the water looks glass-clear, which matters most in high-tech tanks running CO2. The trick is skimming the surface without creating a current that uproots plants or a strong pull that traps shrimp. Look for a compact self-contained skimmer, a gentle adjustable pull, and a shrimp-safe intake.
