Air Stone Disk 132mm

The Air Stone Disk 132mm is a large-format air diffuser stone built for serious aeration in aquariums, ponds, hydroponics, and aquaponics setups. At 132mm across and just 20mm thick, the flat disc profile sits neatly on the bottom of a tank or pond bed and produces broad, even fine bubbles that oxygenate water efficiently across a wide area.

These are the type of airstones we rely on in store, and we recommend them for anyone needing reliable, no-fuss aeration across a larger volume of water. Whether you are running a heavily stocked pond, a hydroponic grow system, or a large display aquarium, this disc will handle the job without complaint.

Connect to any standard air pump via airline tubing for immediate results. Compatible with both freshwater and saltwater setups.
