I bought a garden pond via diaphragm pump and air stone to keep the tube free of ice. Pro: -also in cold flexible -elastischer than the normal aquarium hoses -druckstabil
Contraindications: -The cross-section of the hose is not around at all points. More than half of Schauches is more oval in cross-section. to relocate -schlechter
The positive aspects predominate. I would buy it again.
