Canadianpond.ca's Guide to Choosing a Diffuser System

Choosing the correct diffuser system for the application is critical to the best design for your project. Microbubbles created by either linear Bubble Tubing or micro holes found in diffuser discs give you the best oxygen transfer rates available. Here is a quick guide that should help you decide which system is best for your project.

Basin or Lake Bottom Topography:

Use bubble tubing when slope is very gentle to flat, or when the slope difference is less than 1-2 feet. Bubble tubing is ideal for aerating around a dock or in a constructed basin where it can be laid to follow basin limits or a designated pattern.
Use a disc diffuser in a deep, steep sloped lake where it can lay flat on the bottom.
For narrow lakes or canals use bubble tubing.

Size of Basin or Lake:

For large lake projects you can use either bubble tubing or diffuser disc systems. Bubble tubing comes in ½” or ¾” sizes and diffuser discs come in single 9” or 12” diameter, in a co-active system of two joined 9” discs or in an extreme lift arrangement of 4 joined 9” discs. In our complete aeration systems, the compressor is sized in conjunction with the aeration diffuser for the optimum performance. Bubble tubing can be used in place of diffuser discs.

Depth of Basin or Lake:

For shallow applications use bubble tubing.

For medium to very deep applications use either bubble tubing of diffuser discs.

Aerating Around Structures:

Use bubble tubing to aerate around dock pilings, boats of any size, in any application where flexible linear aeration is a must. If you are not sure, simply ask us and we will be glad to discuss options with you.
