Venturis are an efficient way to deliver air to your fish tank. They also do a great job of delivering O2 to and agitating the bio media in moving bed bio-reactors.
These venturis are designed to run with flow rates above 5000lph/1320gph. From my experience, they will also run well at lower flow rates down to 1500lph/396gph.
While these may be more expensive than some venturis for sale online, the Turbo Venturi-Injector is designed for use in aquaculture.
I have found the 25mm Turbo Venturi-Injector to be far superior in aerating the water than the cheaper venturis made for liquid “injection” that others recommend for use in aquaponics.

Connecting these venturis is easy by using small sections of hose and hose clamps.
It’s a good idea to use 316 stainless clamps where they will be used in water to prevent corrosion.
Venturi in Action
In this clip I demonstrated this venturi as well as a few different DIY units that I’ve found effective at adding a bit of supplemental air into the system.
A big THANKS needs to go to CC Bear from the Backyard Aquaponics Forum for the first DIY unit shown in the clip.
