The Oase CrystalSkim 600 serves as an effective internal filter for your aquarium, efficiently removing unwanted particles such as biofilm, fine plant debris, and surface scum from the water's surface.

It can accommodate aquariums with a capacity of up to 650 liters and boasts a maximum flow rate of 680 liters per hour. Its unobtrusive design enables it to blend seamlessly into the background, without disrupting the aesthetic of your tank.

The skimmer's motor is both robust and quiet, and can be easily adjusted to your desired level of performance using the turning hat of the skimmer. With the manufacturer's 3-year guarantee, you can rest assured that it will keep your water surface crystal clear for many years to come.

The floating ring automatically adjusts to the current water level, and the skimmer can handle extended periods without maintenance. Additionally, the integrated basket prevents any inhabitants from entering the skimmer, making it a reliable and hassle-free addition to your aquarium.
