The OASE CrystalSkim 350 is a compact surface skimmer designed for freshwater aquariums up to 350 litres per hour. It removes surface film, debris, and organic matter efficiently, keeping the water surface clean and clear.

  • 350 l/h flow rate provides effective surface cleaning for small to medium freshwater tanks

    • 0.43 kg lightweight construction ensures stable placement without stressing the aquarium rim
    • Black finish blends seamlessly into most aquarium setups

    What makes the CrystalSkim 350 stand out

    Unlike internal filters that draw water from below, the CrystalSkim 350 works exclusively at the water surface, where debris and protein film accumulate first. Its low-profile 3.6 cm height allows it to sit flat against the aquarium glass without blocking light or sightlines.

    Ideal for

    The CrystalSkim 350 is ideal for freshwater aquarium owners who need a quiet, unobtrusive surface skimmer for tanks up to 350 litres. It suits nano and desktop aquariums where space is limited and every centimetre counts.

    Application of OASE CrystalSkim 350

    Place the skimmer at the waterline of the aquarium so that the intake lip sits just at the surface. Connect the outlet hose to a filter or drain point. The unit operates without electricity — it relies on the natural water flow from the filter system to draw surface water and debris through the skimmer chamber.

OASE is a German manufacturer specialising in aquarium filtration, water treatment, and pond technology products. The brand is widely distributed across European pet retail channels and is known for producing reliable freshwater and marine filtration equipment.
