Hang Filter Slim 2 – flat cascade filter, 300 l/h

This flat filter suits keepers with tanks up to 75 l who have little room behind the aquarium, such as a gap between the glass and a cabinet wall. Its 35 mm depth outside the tank leaves the front and sides of the aquarium clear, and it works with both freshwater and saltwater setups.

Why it matters

• Dual intake: one inlet draws water from the surface and another from mid-water, so the filter processes both layers.
• Two filter inserts: each insert combines activated carbon with filter fleece, and both run at the same time.
• Cascade return: water falls back into the tank in a cascade, which aerates it. According to the supplier, this can make a separate air pump unnecessary.
• Adjustable flow: a flow regulator sets output between 50 and 300 l/h to match tank size and the level of contamination.

What it works with

The filter is intended for freshwater and saltwater tanks up to 75 l. Because the flow can be reduced to 50 l/h, it fits smaller and more lightly stocked tanks, and the 300 l/h maximum covers the upper end of that range. The inserts are standard activated carbon and fleece, so the filter can also take other media that fit its container.
