Colorite Aero-Tube Diffuser Grid

Divide your total required air flow by 750 LPM per grid — each grid holds 20 m of Aero-Tube running at 37 LPM per metre at 1 PSI.

Colorite does not publish a bubble diameter for Aero-Tube — if you need a stated sub-0.5 mm microbubble, look at Bubbletech Oxyprax or Airprax instead.

The Aero-Tube in the grid runs at 1 PSI, plus enough pressure to overcome the water depth the grid is set at.

Lift the grid and flush the tubing through with air or water to clear debris — there are no consumable parts to replace.

Aero-Tube is bulk tubing by the metre, the Aero-Tube Diffuser is a short pre-made weighted length with a barb fitting, and the Diffuser Grid is this pre-assembled HDPE grid holding 20 m of tube on a 50 mm slip connection.

No — the steel frame shown in the photo is not supplied; the grid is the HDPE body with 20 m of Aero-Tube already fitted.

Through a 50 mm slip connection, so it plumbs straight into standard 50 mm pipework.
