Browse aquarium air stones, air diffusers and bubble curtains at The Tech Den Australia. Compare compact sand and ceramic air stones, round balls, PVC-encased discs, mineral airstones and flexible bubble walls from Aqua One, Bioscape and Eheim.
Choose from small single air stones and multipacks through to longer mineral and ceramic designs. Round, ball and disc shapes offer different ways to position bubbles within your fish tank. The range also includes an Eheim air pump diffuser and a Bioscape limewood air stone.
Check each listing for dimensions, connection requirements and intended use. Match the diffuser to your air pump's output and the depth where it will operate rather than assuming every air stone works equally well with every pump.
Aqua One and Bioscape flexible air curtains can create a line of bubbles or be shaped around aquarium features. Select a length that fits your layout and use suitable supports to keep the curtain in position.
For a decorative display, compare Aqua One LED bubble curtains and the Bioscape LED bubble ring. These combine bubbles with changing-colour lighting. Check the electrical supply and air connection requirements separately: power for the LEDs does not replace the air pump needed to produce bubbles.
Related products include the Bioscape Tropic 3000 dual-outlet air pump, airline suction cups and Bioscape bubble wall suction cups. Check whether your chosen listing includes a pump, airline or mounting accessories, and purchase any required components separately.
Air stones and bubble curtains need a suitable air pump and airline to operate. Compare pump capacity, the number of outlets, diffuser requirements and placement before buying. Follow the pump manufacturer's installation instructions, including back-siphon protection where required.
Use the instructions for the exact product for preparation, cleaning and replacement. Choose the size and style that suit your aquarium and ask our team if you need help matching an air stone or bubble curtain to your existing equipment.
