## Summary description

Round 30 mm AQUA DELLA air stone in blue for aquarium aeration. Made to produce fine bubbles when connected to an air pump via tubing, it improves water oxygenation and circulation for fish, shrimp and planted tanks. Suitable for use in freshwater and marine setups as a simple, passive aeration and diffusion accessory.

## Long description

The AQUA DELLA Air Stone round 30 mm blue is a compact aquarium aeration accessory designed to generate fine bubbles when connected to an external air pump via standard tubing. Its small, circular form factor and blue finish make it suitable for discreet placement in fish tanks, shrimp tanks and planted aquaria. The air stone improves gas exchange at the water surface and assists gentle circulation, supporting oxygenation for aquatic life in both freshwater and marine setups.
Advantages
This round air stone produces a steady stream of fine bubbles that enhance oxygen distribution and reduce dead zones in the aquarium. Its compact 30 mm diameter fits easily under ornaments or behind rockwork and vegetation. The device is passive, needs only an air line and pump to operate, and is simple to install or reposition. The blue colour provides a neutral visual accent that blends with many aquarium layouts.
Suitable for
Small to medium freshwater aquariums where supplemental aeration is needed
Shrimp tanks and breeding setups requiring gentle circulation
Planted tanks where discreet oxygenation and surface agitation are preferred
Marine nano tanks and small reef systems for localised aeration
When it may not be suitable
This air stone is intended for passive aeration and is not a replacement for biological or mechanical filtration. In very large aquaria or systems with high oxygen demand it may not provide sufficient aeration alone; a stronger air output or multiple stones will be required. The small size also limits the volume of microbubbles produced compared with larger diffusers designed for high-efficiency gas exchange.
Key specifications
Shape: round
Diameter: 30 mm
Colour: blue
Material type: porous aeration medium (rigid or ceramic composite)
Connection: standard airline tubing compatible
Intended use: aquarium aeration and diffusion in freshwater and marine setups
How to use
Attach one end of standard airline tubing to an external air pump and the other end to the air stone. Submerge the air stone in the desired location, ensuring it sits securely on the substrate or is fixed behind décor to reduce movement. Adjust the pump output or add an inline valve to control bubble size and flow. Periodically check the stone for clogging from detritus or biofilm and clean or replace it when bubble output decreases noticeably.
What to consider before purchase
Size of the aquarium and required air output — may need multiple stones for larger tanks
Compatibility with existing air pump and tubing diameter
Placement options in planted or decorated tanks to avoid disturbing sensitive plants or livestock
Maintenance frequency based on tank conditions and biofilm accumulation
Usage recommendations
Use with a reliable air pump and an adjustable valve to match bubble production to tank needs. For even distribution in medium or large tanks, place multiple stones in different zones. Clean the stone gently by soaking in diluted vinegar or tank water and brushing if buildup occurs; avoid aggressive chemicals that could harm aquatic life.
