This self-sinking tubing has two rows of tiny holes 1/2” apart along the entire length of the tubing and when air from the compressor fills the tubing the holes open and release tiny air bubbles into the water. As these bubbles rise together they create a moving water column with a vacuum effect that pulls water from lower depths towards the surface. It contains no lead or dangerous heavy metals.

Self-sinking & Kink-free air feeder hose for use with Bubble Tubing®
Self-weighted tubing sinks to the bottom on its own -- so you don’t need to tie bricks or weights to make the tubing sink -- like standard PVC tubing which floats when filled with air.
The tubing is constructed of a high-density flexible PVC composite. This allows it to be installed easily and an excellent choice for aeration systems.
The self-weighted tubing rests on the bottom out of sight and out of the way of swimmers and boats. It’s black color makes it invisible from the surface – leaving your water looking natural.
Typical Application Scenario - Aeration and Circulation
Linear Aeration is a fairly recent term used to define aeration with long lengths of diffuser tubing. The principal function of the diffuser tubing or Bubble Tubing® is to aerate by adding dissolved oxygen into the water and to create circulation.
Ecological sludge removal by diffused linear aeration is a cutting-edge technique for reducing large volumes of nutrient rich, organic sediment from ponds and lakes.
Bubble Tubing® can also be installed in large shallow wastewater treatment basins and aquaculture aeration applications.
Bubble Tubing® can be used as a replacement with traditional aeration diffuser systems -- like membrane discs and air-stones. Bubble Tubing® is the easiest and least expensive way to maintain highly efficient linear aeration.


Typical Application Scenario - De-icing of Docks & Water Structures
For de-icing – one or several lengths of Bubble Tubing® is placed under or around the dock to circulate the deeper warmer water. This circulation provides and open area free of ice which prevents ice expansion damage to docks, boat slips, etc.
Open areas in the ice also promotes winter oxygen diffusion and a means for harmful gas to escape. The oxygen depletion and harmful gas is caused by decomposing leaves, dead algae, fish waste, etc.. This combination can become a lethal – resulting in winter fish kills.
Keeping areas of water open attracts waterfowl and other winter wildlife.
Additional Application Scenarios
- Wastewater basins, composting and storm-water retention ponds can achieve highly efficient aeration and circulation using Bubble Tubing®. Tubing can be installed directly in to the basin or attached to grids to allow quick removal when required.
- Combining linear aeration with floating islands is a recipe for a healthy pond!
- Bubble curtains can be effective in deflecting floating aquatic debris.
