  • Flexible: Can be installed horizontally, making it suitable for use in paludariums
  • Economical: Extremely quiet and energy-efficient pump
  • Adjustable: water flow rate can be adjusted individually on the water diffuser
  • Optimal filtration: Effective water filtration
  • Efficient: Large filter surface in the smallest space for effective water filtration

The Oase BioCompact 25 Internal Aquarium Filter is perfect for smaller cold water, tropical and marine aquariums up to 25 litres. This compact filter is extremely quiet and energy efficient and despite its small size the BioCompact 25 offers effective filtration thanks to its large filter media surface area.

The BioCompact 25 Filter consists of 2 stages: a coarse foam pre filter and a fine activated carbon foam filter. The flow rate can be easily adjusted via the built in flow regulator and the integral flow diffuser helps to improve aeration through increased surface agitation. The Oase BioCompact Filters include suction cups for securing to the aquarium glass and unlike other filters they have the ability to be installed horizontally in a tank, making it ideal for Paludariums or aquariums where water depth may be an issue.

tiny tank filter

Bought for a small temper tank ( 12"x8"x8") and found this filter to deliver a good flow rate so that the fish could play in the water movement and it was easy to keep clean and access the filter pads. Im normally an ehiem fanatic but will look at these in future.
