The newly developed Dennerle lily pipe fulfils all the requirements: Rotates flexibly through 180°. This allows optimum alignment of the water flow. It is also vertically adjustable (max. 10 mm) to adapt to the water level.
Daytime position: if the filter is connected to the bottom catch, the lily pipe outlet is completely under water. Thanks to its fanned out shape, the lily pipe also creates a gentle, natural, plant-friendly water flow that supports moderate gas exchange. This means the CO2 needed by the plants is not excessively driven out.
Night time position: by raising the top clip the lily pipe is not fully under water. This creates a small whirlpool that removes any possible mould residue and introduces additional oxygen into the aquarium.
