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
