AQUA DELLA aquarium suction cups, black, 32×22 mm, pack of 50

AQUA DELLA aquarium suction cups, black, 32×22 mm, pack of 50 are flexible mounting supports designed for secure, temporary attachment of tubes, heaters, air lines and small accessories to smooth aquarium glass and acrylic surfaces. Each suction cup has a compact profile that fits a range of aquarium equipment and ensures stable contact with the tank wall while resisting continuous exposure to water in both freshwater and marine environments.

Advantages

These suction cups are made from a soft, flexible material that conforms to curved or slightly uneven surfaces to improve grip. The compact 32×22 mm size balances holding power and low visual impact so equipment stays organized without obstructing the view. Sold in a pack of 50, the set provides multiple mounting points for routing tubing, securing heaters and fixing small accessories. The black color reduces visibility behind decorations and plantings while maintaining a neutral appearance in most aquarium setups.

Suitable for

• Fixing airline tubing and silicone hoses to tank walls
• Supporting small aquarium heaters and temperature sensors
• Organizing filter inlet/outlet pipes and intake tubes
• Mounting LED or small accessory cables discreetly
• Temporary attachment of ornaments or background elements

How to use

Clean the target area on the aquarium wall to remove algae, dust or film and dry the surface briefly for best initial adhesion. Press the suction cup firmly against the glass or acrylic to expel trapped air and create a vacuum seal. Attach tubing, cables or small accessories by threading them through the suction cup’s mounting feature or applying gently to the cup’s face according to the accessory shape. Check the attachment periodically and reseat the cup if it begins to lose suction.

Usage recommendations

For long-term stability, avoid placing heavy loads on a single suction cup; distribute weight across multiple cups. Reposition and clean suction cups and the contact surface every few weeks to prevent slipping caused by biofilm or mineral deposits. Use extra cups in marine tanks where water movement and salinity can reduce suction strength over time.
