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
