Description
Aqua One Ceramic Airstone 4" (10cm) is a compact air diffuser designed to turn airflow into a fine stream of bubbles for improved aeration. It’s a simple, reliable way to increase dissolved oxygen in nutrient reservoirs, water features, and aquarium setups.
Why you’ll like it
- Fine bubble diffusion helps increase dissolved oxygen in water
- Compact 10cm size suits smaller reservoirs and tanks
- Ceramic construction for consistent airflow dispersion
- Easy, low-maintenance aeration upgrade
Best for
- DWC reservoirs, nutrient tanks, and smaller tubs needing aeration
- Supplementing aeration in larger reservoirs (use multiple stones)
- Aquariums, sumps, and water features
- Growers wanting steadier oxygenation without complicated changes
How to use
Connect the airstone to an air pump using airline tubing, then place it on the bottom of your reservoir/tank for the most even bubble spread.
- Run an appropriately sized air pump for your water volume
- If bubbles are uneven, soak the airstone in clean water before first use
- Keep it positioned so it stays fully submerged
- Clean or replace if it becomes clogged over time (flow drops noticeably)
Compatibility
- Hydro: Yes (DWC/RDWC reservoirs, nutrient tanks)
- Coco: Indirect (for reservoir aeration only)
- Soil: Indirect (for water storage/holding tanks only)
- Systems: Works with air pumps and airline tubing (assumption: standard airline connection)
What’s included
- 1 x Aqua One Ceramic Airstone 4" (10cm) (QB-10)
Notes
- Air pump, airline tubing, and non-return (check) valve are not included
- Use a check valve if the air pump sits below the waterline to help prevent back-siphoning
- Rinse before first use; avoid harsh chemicals that can block the pores
- Performance depends on air pump size, tubing length, and water depth
