Air Stone Usage Tips

1. First Use: Soak the air stone in water for 24 hours before connecting it to your air pump. This allows any trapped air to escape fully, ensuring maximum bubble output from the start.
2. Maintenance: If bubble output decreases over time, simply remove the stone, rinse and clean it thoroughly, then reinsert — it'll perform like new.
3. Dual-Output Pumps: For air pumps with two outlets, use a T-junction connector to combine both air outlets and increase total air volume for larger tanks.

Wide Applications

These versatile air stones are ideal for:

• Freshwater and saltwater fish tanks
• Hydroponics and aquaponics systems
• Shrimp tanks and live coral reef tanks
• Breeding tanks and hospital tanks
• Water gardens and decorative ponds

Frequently Asked Questions

Q: How many aquarium air stones come in this pack?

A: Each order includes 10 cylinder-shaped aquarium air stones. Airline tubing, air pump, and other accessories are not included.

Q: What size airline tubing do these air stones fit?

A: These air stones are compatible with standard 4/6 mm (3/16" inner diameter) oxygen airline tubing, which is the most common size used with aquarium aerator pumps.

Q: Do I need to prepare the air stones before first use?

A: Yes! For best performance, soak each air stone in water for 24 hours before connecting it to your air pump. This allows the stone to fully absorb water and expel trapped air, resulting in an optimal, consistent bubble stream.

Q: Can these air stones be used in hydroponics systems?

A: Absolutely. These cylinder air stones are designed for both aquarium and hydroponics use, providing efficient oxygen diffusion in water reservoirs to support plant root health and aquatic life alike.

Q: How do I clean and maintain the aquarium air stones?

A: If you notice a reduction in bubble output, remove the air stone from the tank and rinse it under clean water, gently scrubbing any mineral buildup. Allow it to dry briefly, then re-soak before placing back in the tank. Regular cleaning extends the life of each stone significantly.
