With the compact and easy-to-attach Hydor Slim Skim Nano Aquarium Internal Protein Skimmer， you can keep your nano and mini reef aquariums healthy and free of debris. This skimmer uses a fish-safe special grid to draw in water from the surface and a powerful and efficient multi venturi impeller to help improve the water quality. It’s easily secured to the side of the tank with an innovative magnetic suction cup and won’t disrupt your aquarium inhabitants thanks to the built-in anti-vibration system.

HAZARDS TO HUMANS: Before installation or maintenance， or before putting your hands into the aquarium， remove the power supply from all the electrical devices under water.
