Aquarium Hose AQUA DELLA flexible 12/16 mm, length 3 m

The AQUA DELLA flexible aquarium hose with inner/outer diameters of 12/16 mm and a length of 3 m is a transparent, bendable tubing intended for water circulation and general aquarium plumbing. It is suitable for connecting pumps, external and internal filters, siphons and air lines where a flexible, corrosion-resistant hose is required. The hose construction allows gentle bends without kinking and provides reliable water flow for freshwater and marine setups.

Advantages

This flexible aquarium hose is made from materials resistant to corrosion and typical aquarium chemicals, keeping clarity and flexibility over time. Its 12/16 mm inner/outer diameter sizing matches common aquarium fittings and adapters, enabling straightforward connections to pumps, filter outlets and intake nozzles. The 3 m length offers sufficient reach for most home aquaria while remaining easy to route and trim to size.

Suitable for

• Connecting external or internal aquarium filters to inlets and outlets
• Pump discharge lines and small circulation setups
• Siphoning for water changes and substrate cleaning
• Air lines for diffuse aeration when used with appropriate fittings

When it may not be suitable

This hose may not be appropriate where very high-pressure operation is required, such as high-pressure pond pumps or pressurised systems beyond typical aquarium use. It is not intended as a rigid plumbing solution where fixed, non-flexible piping is required for structural reasons.

Key specifications

• Inner diameter: 12 mm
• Outer diameter: 16 mm
• Length: 3 m
• Material: flexible, corrosion-resistant aquarium-grade tubing
• Colour: transparent/clear

How to use

Measure and cut the hose to the required length with a sharp utility knife or hose cutter to ensure a clean, straight end. Push the hose firmly onto pump or filter barbs and secure with hose clamps or spring clips where a tight seal is needed. For siphoning, attach the hose to a siphon assembly or use manual priming techniques. Rout the hose to avoid sharp kinks and secure it to legs or aquarium fixtures if necessary to prevent movement.

What to consider before purchase

• Confirm that 12/16 mm inner/outer diameters match your pump, filter or fitting dimensions.
• Decide whether 3 m length is sufficient or if additional connectors are needed for longer runs.
• Consider using hose clamps for pressured connections or where a leak-proof seal is required.

Usage recommendations

Regularly inspect the hose for signs of wear, clouding or softening and replace it if deterioration occurs. Clean with aquarium-safe methods and avoid exposure to direct sunlight for prolonged periods to extend service life.
