This 4-in-1 internal corner filter suits aquarists with tanks of 40 to 80 litres who want one unit to handle clarity, filtration and aeration. Its compact corner body is easy to conceal, which matters most in smaller tanks, and the setup and routine maintenance are designed to be manageable for keepers without prior experience.
Why it matters
- Adjustable output: a knob on top of the filter sets the pumping rate from 50 to 260 l/h, so the flow can be matched to the tank size and layout.
- Directional outlet: the water stream can be turned within a 90° arc.
- Four media compartments: sponge for mechanical filtration, bio-ceramic for biological filtration, activated carbon for chemical filtration and fleece for fine clarification. Each medium has its own slot, so they can be cleaned separately.
- Two outlets and air supply: a strong jet outlet covers the far end of the tank, while the rain bar breaks up the stream and adds aeration. A supplied air tube and valve control the air intake.
