Concave HMF with air lift

**To operate the HMF filter with air lift, you will need an air pump (diaphragm pump), which is not included in the scope of delivery!

With the "Concave Line" filter series, Aquakallax offers you the world's first fully active, space-saving HMF.

Attention!!! You can easily determine the correct filter height by measuring from the bottom of the tank to the waterline. When installed, the filter rests on the gravel/sand and extends approximately 2 cm above the water surface.
