This Aquarium Oxygen Bubble Stone Set provides practical aeration for freshwater tanks. The kit includes ceramic stones in assorted sizes, from 3 cm to 13 cm in diameter, letting you tailor placement to your tank layout.
Use these stones to diffuse air from a small pump, increasing dissolved oxygen and improving water circulation for fish and shrimp. The frosted surface resists algae buildup and cleans easily, while the steady foam helps indicate airflow.
- Ceramic stones sintered at high temperature for durability.
- Assorted sizes (3–13 cm) for flexible placement in corners or along filter outputs.
- Single-hole air intake connected to 4 mm tubing for simple setup.
- Large air output with fine foam to provide gentle agitation without excessive turbulence.
- 3–6 cm stones are suitable for 2W pumps; for 4W+ pumps, position up to 8 cm above intake.
- Easy to clean and designed for long-term freshwater use.
Fit: compatible with standard 4 mm airline tubing and common aquarium pumps.
