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)

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 6" (15cm)

Notes

  • SKU code shown as QB-12 in the screenshot (assumption: internal listing code)
  • 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
