Sale price$9.99

Description

Aqua One Ceramic Airstone 12" (30cm) is a long, porous air diffuser designed to break airflow into a fine stream of bubbles for improved aeration. It’s a simple, reliable add-on for oxygenating nutrient reservoirs, water features, and aquarium setups.

Why you’ll like it

  • Fine bubble diffusion helps increase dissolved oxygen in water
  • Long 30cm format provides more even aeration across larger areas
  • Ceramic construction for consistent airflow dispersion
  • Easy, low-maintenance way to support healthier root-zone water conditions

Best for

  • DWC and RDWC reservoirs needing stronger aeration
  • Large tubs/reservoirs where a small round airstone won’t cover enough area
  • Aquariums, sumps, and water features
  • Growers wanting steadier oxygenation without complicated upgrades

How to use

Connect the airstone to an air pump using suitable 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 use
  • Keep it weighted/positioned so it stays submerged and level
  • 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 12" (30cm) (QB-12)

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
