Scapers Flow – Hangon-Filter

Backpack external filter for freshwater aquaria

An aquarium without technology is not possible, but with the Dennerle Scaper's Flow we banish the filter technology to the outside. For every situation, whether with a black or transparent background, the backpack filter comes with the right intake tubes and Lily Pipe. The filter is equipped with all filter materials and comes pre-assembled for immediate use.

Lily Pipe fully submerged

In this position the lily pipe generates gentle, natural currents below the water’s surface. Minimal surface movement prevents unnecessary CO₂ loss.

Lily Pipe approximately ⅔ submerged

The “rippling” water return in this position delivers a rapid supply of oxygen. This is an important emergency measure if there is a lack of oxygen, as indicated by fish breathing faster.
Vortices are formed that drag surface residues (film) under water, which are then filtered out.

Tip

Hang the filter in the lower position during the day, switching to the upper position at night. This saves you valuable CO₂ during the day. At night, when plants do not consume any CO₂ but instead require oxygen just like your fish, the water is enriched with oxygen.
Lily pipes can be adjusted up or down by around 10 mm in line with water levels, and they can also be rotated. Lily pipes should be positioned so as to generate even, gentle water currents throughout the entire aquarium.
