Product description
The SlimFlow 200 clips onto the back of a nano tank and takes up only 7 cm behind the glass. Flow is adjustable from a gentle trickle for bettas and shrimp up to the full 200 L/h, and the removable surface skimmer keeps the protein film off the water.
Media sits in a single pull-out cartridge: a coarse sponge in front of a BioRing basket, so you can rinse the sponge weekly and leave the biological media untouched.
In the box: filter body, pump, sponge, BioRing cartridge, surface skimmer and a spare impeller.

Silent and tiny
I cannot hear it at all from a metre away. The skimmer actually works, no more oily film on my 30 L.

Good, but the clip is fiddly
Filtration is fine. Getting it to sit level on 6 mm glass took some fiddling with the spacer.
