Bioscape Bubbler Red Volcano
Adds a bubbling volcano feature and extra tank oxygen. The Bioscape Bubbler Red Volcano is a cast-resin aquarium ornament shaped like an erupting volcano, with an air-stone diffuser built into its base. Connected to a standard aquarium air pump, it releases a steady curtain of fine bubbles for movement, surface agitation and a lit-look centrepiece in freshwater and marine tanks.
Key features
- Built-in air-stone bubbler – connects to any standard aquarium air pump via airline tubing to release a steady stream of fine bubbles.
- Aquarium-safe resin – cast in non-toxic resin rated for long-term submersion in both freshwater and marine tanks.
- Bold volcano silhouette – a red-toned eruption shape designed to read as a feature piece rather than background decor.
- Adds surface agitation – the rising bubble column helps move water and support gas exchange around the ornament.
- No separate power draw – runs off your existing air pump; it doesn't need its own mains connection.
What's included, and what you'll still need
- Included: the resin volcano ornament, with the air-stone diffuser built into its base.
- Not included: an air pump, airline tubing and a check valve – all needed to run it, and all sold separately.
Setting it up
Rinse the ornament before placing it in the tank. Run airline tubing from an aquarium air pump to the inlet nozzle at the base, and fit an inline check valve if the pump sits below the water line, to stop water siphoning back into the pump when it's switched off. Use the pump's own air control, or an inline gang valve, to set how heavy the bubble stream is.
Suitable for, and not suitable for
- Suitable for: freshwater and marine aquariums, as a static bubbling ornament run off an external air pump.
- Not suitable for: tanks with no spare air pump outlet – on its own, without an air source connected, it's decor only and won't bubble. Weigh up the extra flow in small shrimp-only or betta tanks, where a gentle bubble rate usually suits better than a strong one.
Care and maintenance
Rinse the ornament in aquarium water (not tap water or detergent) during routine maintenance to clear algae film. If the bubble stream slows or turns erratic, the diffuser is usually clogging with biofilm – because it's cast into the resin rather than a separate replaceable stone, a badly clogged ornament typically needs replacing rather than re-diffusing.
Warranty and delivery
Covered by your consumer guarantee rights under Australian Consumer Law if it arrives faulty or not as described. Ships as a small parcel.
Common questions
Does this come with an air pump?
No. The Bubbler Red Volcano is the resin ornament only – you'll need a separate aquarium air pump, airline tubing and, ideally, a check valve to run it.
Is it safe for a marine or reef tank?
Yes. The resin is cast for long-term submersion in both freshwater and marine setups.
Why has the bubble stream stopped or slowed down?
Most often it's the built-in diffuser clogging with biofilm, or the air pump's diaphragm wearing out. Try a stronger pump first; if the stream stays weak or uneven, the ornament's diffuser is the likely cause.
Can I control how many bubbles it makes?
Yes – the bubble rate is set by your air pump's own airflow control, or by fitting an inline valve on the airline between the pump and the ornament.
