Aquarium Suction Cups Aliga 20×30 mm, transparent, pack of 50

Transparent aquarium suction cups by Aliga, size 20×30 mm, supplied in a pack of 50. These suction cups are designed to attach tubes, ornaments, heaters or cables to aquarium glass or acrylic surfaces. Made from a flexible material that provides a reliable grip while allowing easy repositioning, they are suitable for both freshwater and marine aquariums where small secure mounts are required.

Advantages

The transparent design minimizes visual impact inside the aquarium and helps preserve the natural appearance of the setup. Flexible material ensures consistent suction on smooth surfaces and reduces the risk of cracks or chips on glass or acrylic. Supplied in a bulk pack of 50, the set provides multiple mounting points for tubing, air lines or decorative elements, enabling tidy cable management and stable positioning of equipment.

How to use

Ensure the glass or acrylic surface is clean and free of algae, dust or residues before applying the suction cup. Wet the suction cup slightly or apply a thin film of water to the contact surface to improve adhesion, press firmly against the tank wall and hold for a few seconds to establish suction. Position tubing, small heaters or decorations into the suction cup’s mounting area and verify stability. To remove or reposition, gently lift an edge of the suction cup to break the seal and reapply in a new location.

Usage recommendations

For best long-term performance, periodically check suction points for looseness, especially in warm water or under direct flow from filters and pumps. Replace suction cups showing cracks, hardening or loss of elasticity. Avoid using suction cups on rough, porous or heavily textured surfaces, and do not overload individual cups with excessive weight beyond small tubing or lightweight ornaments.
