Bioscape Airline Suction Cups 2 Pack
Small clips that keep airline tubing pinned neatly to the glass, out of sight and out of the way. These Bioscape airline suction cups grip standard airline and CO2 diffuser tubing at the point it meets the aquarium or pond, so hoses run straight down the back pane instead of drifting across the display.
Key features
- 12 mm suction disc — sized to grip glass and acrylic without crowding a nano tank.
- Slotted clip — the airline slides in and holds firm without a separate tie or clamp.
- Two pack — enough to secure a single airline run at two points, or two separate runs.
- Reusable — lifts and repositions cleanly on clean glass.

Suitable for, and not suitable for
Suitable for freshwater and marine aquariums, and outdoor ponds, on clean glass or acrylic.
Not suitable for heavily algae-coated, scratched or oily glass — the cup will not hold a reliable seal.
Care and maintenance
Soak the cups in warm water for 5–10 minutes before first use to soften the plastic and improve the seal. Press onto clean, algae-free glass for the strongest hold — expect months of grip on a clean surface, only hours on a dirty one. Reclean the glass and cup if the hold weakens.
Warranty and delivery
Covered by consumer guarantees under Australian Consumer Law. Ships as a standard parcel.
Common questions
Will these hold a CO2 diffuser in place?
Yes — the slotted clip accepts standard diffuser and airline tubing, though a heavier diffuser body is best supported with a second cup.
Do they work on acrylic tanks?
Yes, the same suction principle applies to clean acrylic as well as glass.
Why has the grip weakened after a few months?
Algae film or mineral deposits under the cup break the seal. Clean both the glass and the cup and it will grip again.
