The Patented Random Flow-Generator® Nozzle

The Random Flow Generator® Nozzle

The Only Random Flow Device With No Moving Parts.
The unique patented internal design of the Random Flow Generator® by Vivid Creative Aquatics, leverages fluid dynamics to randomly alter the direction of the flow as it exits the nozzle.

This internal helix design, pulls the central jet in on of 5 possible direction, but in only one direction at a time. The result is a broad wave-maker like motion but with no moving parts to wear out, no noise and no addition heat generated.

The Random Flow Generator® or RFG Nozzle can help to create a more natural, randomized flow pattern within an aquarium, pond, or other bodies of water.

Easy-Snap Fitting

This Reandom Flow Generator Nozzle is desgined to snaps onto a genuine Loc-Line® modular hose fittings. No tool required.
