Description
Aqua One Ceramic Airstone 6" (15cm) is a compact air diffuser designed to break airflow into a fine stream of bubbles for improved aeration. It’s a straightforward 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
- 15cm length provides broader aeration than smaller stones
- Ceramic construction for consistent airflow dispersion
- Easy, low-maintenance aeration upgrade
Best for
- DWC/RDWC reservoirs and nutrient tanks needing dependable aeration
- Medium tubs/reservoirs where wider bubble spread is useful
- Aquariums, sumps, and water features
- Growers wanting steadier oxygenation with simple hardware
How to use
Connect the airstone to an air pump using airline tubing, then place it on the bottom of your reservoir/tank for even bubble distribution.
- Run an appropriately sized air pump for your water volume
- Soak in clean water before first use if needed for even bubbling
- Keep it fully submerged and positioned flat
- Clean or replace if it clogs over time (flow drops noticeably)
