Fine bubble diffusers such as our Bubble Tubing® produce many tiny air bubbles (between 1 and 3 mm). These tiny bubbles rise steadily from the depths of all manners of aquatic landscapes, from wastewater treatment basins, to waterways, canals, ponds, lakes and lagoons. These bubbles provide a substantial and efficient mass transfer of oxygen into water. This oxygen, combined with organic nutrient sources, such as sewage and sediments, allows naturally occurring bacteria to produce enzymes to help break these sources down.

Our Bubble Tubing® Products
Bubble Tubing® is sold standard cut, custom per foot, or by rolls of 500′. Contact us for prices and details.
It is also a component of:
- CanadianAir Aeration Systems
- Mini-Air System
- Thawline Bubbler Deicers
- OctoAir Industrial Diffuser for aeration or deicing (embedded in the stainless steel frame)
- SalmoAir® Diffuser for upwelling in Aquaculture
Made using highly resistant and flexible PVC plastic, Bubble Tubing® keeps its shape and does not kink. When entering the tube, the compressed air creates an internal pressure. Precise perforations on both sides, going the entire length of the hose, allow this compressed air to be released in microscopic bubbles. Their size helps prevent the hose from fouling, a common problem seen in porous diffusers. Once released, the rising air forms a uniform bubble curtain that optimizes the transfer of oxygen. It also promotes water circulation throughout the water column, as it creates a rising current.
Using Bubble Tubing® reduces pressure drops and does not require any underwater electricity. Bubble Tubing® offers a superior global aeration performance compared to other aeration devices. Bubble Tubing® reduces power consumption, installation and maintenance costs substantially.
When used in de-icing, the bubbles exiting the Bubble Tubing® drag the denser, heavier and warmer water from the depths to the surface. This movement of warmer water inhibits the formation of ice.
Bubble Tubing® has an excellent Standard Oxygen Transfer Efficiency (SOTE) and a great Standard Aeration Efficiency (SAE).

Bubble Tubing® Test Results
In 2011 we tested the oxygen transfer capabilities of Bubble Tubing® through an independent firm, GSEE Inc of Laverne, Tennessee. The tests were carried out on the ½”, ¾” Bubble tubing® and the OctoAir-10 industrial diffuser. In the summer of 2017 we gave GSEE Inc. another mandate to test the Bubble Tubing® at higher airflows and deeper depths, while also carrying out testing on our 1” Bubble tubing® and OctoAir-60 industrial diffuser.
“Overall, the results obtained for the CanadianPond.ca Products Ltd. aeration systems were uniformly excellent and produced some of the highest SOTE values GSEE Inc. has observed.”

No matter the scale of operations the same basic principle applies: a compressor is connected to Bubble Tubing® through a heat hose line equipped with a check valve. We offer all the necessary products from start to finish to fully set-up a reliable and efficient aeration system for you. We can size the compressor for the application, suggest tubing layout, suggest cost effective design modifications, and offer to troubleshoot. Our experience designing aeration and de-icing systems with Bubble Tubing® is substantial, and our expertise is sought for many aeration projects.
How to install Bubble Tubing (PDF)
Bubble Tubbing® require a compressor, costumers may choose between piston or diaphragm compressor. (Shop compressors here.) Compressor must be installed in a cabinet. This cabinet need to allow good air circulation to avoid overheating and protect de compressor from the weather. (More about cabinets here.) If the compressor is not installed in a cabinet, it is necessary that it is protected by a ventiled shelter. Once the shelter is identified, you will need to mount the compressor on its base and secure it with screws either to the wall, floor or on a shelf. Securing the base prevents the compressor from moving while it is running. It is not recommended to use an extension cord, make sure the electrical outlet is within reach of the compressor and fan wires; 1.8 m (6 feet).
Schematic of a diffuser with Bubble Tubbing®;
Before connecting the Bubble Tubing® to the feeder line, unroll it, making sure it is not twisted. Tubing well straighten allows a uniform dispersion of air through all its length. Let the tubing rest unrolled before the installation of the system.
Bubble Tubing® is also compatible with torpedo. (More about Torpedo here.) If requested in advance, the Bubble Tubing® can already be connected to the check valve (assembly cost may apply).
If installed in a large pond, Bubble Tubbing® installation can be done with a boat. Compressor must be started, unroll the pre-assembled hose to the shore and put the rest of the roll in the boat. While keeping the Torpedo feeder line in hands, go on the water and uncoil the Torpedo line until you reach the desired location for the Bubble Tubbing® diffuser. With the diffuser already connected to the Torpedo air feeder line, slowly continue lowering into the water the diffuser as it self-sinks to the bottom. With the compressor turned on, you should see bubbles and be able to use them as visual reference to make sure the tubing is diffusing through its length.
If installed in a smaller pond, it is also very possible to install the system without a boat. (It is even recommended.) Start the compressor right before installing the diffuser in the water, the bubble will guide you to settle the diffuser at the desired place in the water. TUse a long rope (twice the length of the pond) and a small cord (1 to 2 feet long). Form a loop at the end of the diffuser using the small cord (loop shown in the images below). Pass the long rope through this loop, and while holding both ends of the long rope, use it to pull the diffuser into place in the water. The diffuser will sink into place at the bottom of the water. A second person should be hanging on the feeder line to help with the placement of the diffuser. Once in line with the wanted position, release one end of the long rope and pull on the other end to retrieve your rope.
Do not underestimate positionning of the Bubble Tubing®, air is lazy, it will find the quickest way to go up. Place the Bubble Tubing® at the same depth keeping it as level as possible (maximum 1 foot drop). The tubing can be placed in a circle, curve, or straight line to follow a continuous bathymetric line (level curve at the bottom of the pond). Note that even if the Bubble Tubing® does not bubble evenly, you will still ensure a “vertical” water circulation in your pond. We recommend the use of a "depth finder" tool if you do not know the level curve at the bottom of the pond.
If you install your unit into a body of water that is extremely stratified, use caution as you start it up. Suggested startup time for the unit for a stratified lake might be initially running for 1 hour per day during daylight hours for the first week and gradually increase operation by increment of 1 hour until running continuously. Sunny days are preferable to cloudy days because photosynthesis provides oxygen while the water circulates and mixes. For more information on the soft start procedure, clic here.
