This new technology uses multiple smaller venturis making it more gentle on fish compared to a traditional venturi. Create large amounts of bubbles using smaller water pumps saving on energy costs.  The MacroMixer for fish farming and hatcheries is the most efficient venturi ever designed. This newly designed technology also drastically reduces the high noise levels associated with a single venturi for a much quieter operation.

Simple Setup: Choose between a 1",  1.5", or 2" FPT and attach it to any outflow pump within the recommended pump flow rates.

Not Inline piping: This is not an Inline attachment. It should be used under the water line and as a jet head nozzle on the end of a pipe, hose, or pump. It is not water tight.

The 1" passes solids up to 5.5mm and requires a minimum 3000 LPH pump

The 1.5" passes solids up to 8.5mm and requires a minimum 7000 LPH pump

The 2" passes solids up to 11mm and requires a minimum 16000 LPH pump

Includes an MPT threaded x SLIP adapter for attaching to any PVC pipe
