Weighted vs standard tubing

Airline that stays on the bottom

Standard polytubing wants to float, which leaves your air line drifting up off the pond floor. Weighted airline is built to sink and stay put across the submerged run.

Standard polytubing

Floats and drifts

  • Wants to rise off the pond floor instead of lying flat
  • Line can wander and get in the way
  • Not built for the submerged section of the run
  • Extra effort to keep it weighted down on the bottom

Weighted airline

Sinks and stays put

  • Drops to the bottom and stays there without floating
  • Lies flat across the pond floor and keeps the run tidy
  • Delivers air right where your diffuser needs it
  • Ideal for the underwater section of any aeration run

Weighted airline FAQ

Questions before you buy

Common questions about weighted airline for pond aeration runs.

What is weighted airline?
Weighted airline is aeration tubing built to sink. Where standard polytubing wants to float, weighted airline drops to the bottom and stays put, so it lies flat across the pond floor and delivers air right where your diffuser needs it.
What sizes does weighted airline come in?
It is available in 3/8 inch and 1/2 inch diameters. The 3/8 inch comes in 25 ft, 50 ft, and 100 ft lengths, and the 1/2 inch comes in 25 ft and 50 ft lengths.
When should I use weighted airline instead of standard polytubing?
Use weighted airline for the submerged section of the run, where it needs to sink and stay on the pond bottom. Use standard polytubing for the run from shore to the water.
Why does weighted airline sink when standard tubing floats?
Weighted airline is built to sink and stay on the pond bottom without floating, so the underwater section of your aeration run lies flat and stays out of the way rather than drifting up off the floor.
Which diameter should I choose?
Weighted airline is offered in 3/8 inch and 1/2 inch diameters. Match the diameter to your existing aeration run and diffuser setup, then pick the length that covers the submerged section of your run. The 3/8 inch is available in 25, 50, and 100 ft, and the 1/2 inch in 25 and 50 ft.
