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.

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.
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.
