Suction Cup for Aquarium Green Leaf 12×30 mm, transparent, pack of 50

Transparent suction cup by Green Leaf, size 12×30 mm, supplied in a pack of 50. Designed to secure tubing, air lines, heaters or decorations to aquarium glass or other smooth surfaces, this suction cup offers a compact and unobtrusive mounting point for freshwater and saltwater tanks. The pack of 50 ensures multiple attachment points for hobbyist setups, breeding tanks or small public displays where repeated, removable fixation is required.

Advantages

The suction cup is made from clear, flexible material that provides reliable adhesion on clean, smooth surfaces and remains largely invisible inside the aquarium. Its small 12×30 mm profile allows discreet placement for tubes and cables while minimizing interference with tank inhabitants. Supplied as a bulk pack of 50, it enables consistent anchoring across multiple locations and replacements when needed.

Suitable for

• Securing air tubing and airline connectors
• Fixing heater cables and thermostats to glass
• Mounting lightweight decorations and plants
• Temporary or movable attachment points in aquascaping
• Small hobby and laboratory aquarium assemblies

How to use

Ensure the glass or smooth surface is clean and free of algae, biofilm or dust before attaching the suction cup. Moisten the cup slightly with clean water to improve initial adhesion, press firmly against the surface and seat it until a vacuum is formed. Route tubing, airline or cable through the suction cup's attachment point and adjust position as needed. To remove, gently pull the edge of the cup to break the seal and detach without scraping the glass.

Usage recommendations

For best long-term retention, periodically check and re-seat suction cups during routine maintenance, especially in environments with temperature changes or heavy flow. Replace individual cups from the pack if they harden, lose elasticity or show signs of wear. Avoid using on rough, porous or heavily curved surfaces where a vacuum seal cannot form reliably.
