Description

The Aqua One PVC Encased Air Disk (11.5cm Large) is a broad air diffuser designed to produce an even spread of fine bubbles for improved aeration. The larger disk format helps cover more area across the bottom of a reservoir or tank, supporting steadier dissolved oxygen levels.

Why you’ll like it

  • Large 11.5cm disk for wide, even bubble distribution
  • PVC encased design helps protect the diffuser and keep it stable
  • Fine bubble output supports better dissolved oxygen levels
  • Great option when you want broad aeration from a single diffuser

Best for

  • DWC/RDWC reservoirs and nutrient tanks needing more even aeration
  • Larger tubs/tanks where small airstones don’t provide enough coverage
  • Aquariums, sumps, and water features
  • Growers wanting reliable oxygenation with minimal setup

How to use

Connect the air disk to an air pump using airline tubing, then place it flat on the bottom of your tank/reservoir for the most even bubble spread.

  • Use an air pump sized to run a larger diffuser (general guidance)
  • Soak in clean water before first use if bubbling is uneven
  • Keep it fully submerged and positioned flat
  • Clean or replace if it becomes clogged and airflow drops

Compatibility

  • Hydro: Yes (reservoir aeration)
  • 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 Airstone PVC Air Disk Encased 11.5cm Large (QB-45)

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 diffuser surface
  • Performance depends on air pump size, tubing length, and water depth
