Hiblow Fine Bubble Diffuser DIF500

Bubble Size:

There are 3 main bubble size ranges for diffusers. A fine bubble diffuser produces a bubble up to 3 mm in size. A coarse diffuser has holes with a pore size from 6- 50 mm. In between is considered a medium bubble diffuser (3-6mm)

Fine Bubble Diffuser:

Advantages: Fine bubble diffusers produce many small bubbles that slowly rise to the surface. The high volume provides more surface area as compared to course bubbles, allowing for about 2x’s the amount of oxygen to transfer into the water. The higher oxygen transfer is considered beneficial for ponds with dense fish populations and/or specific breeds of fish that require higher DO levels.

Disadvantages: The small holes add pressure to the aeration system – as much as 1-1.5 PSI per diffuser depending on the type. Also, since the holes are small, mineralization of dissolved solids and biological growth can start to cover or even plug the pores. This restricts air flow and puts even more pressure on the pond aerator which can cause the diaphragms to rupture prematurely. Fine bubble diffusers often need regular maintenance and must be swapped out more frequently than course bubble diffusers. They do not mix the pond as effectively because the small bubbles do not project as far out from the diffuser and are not diffused with the same amount of force.
