Random Flow Generator® Nozzle 3/4″ for Loc-Line®

This 3/4-inch Random Flow Generator® (RFG) Nozzle is designed to create a natural, random flow in aquariums and ponds, with no moving parts. It clips directly onto original 3/4-inch Loc-Line® and is a simple yet highly effective upgrade for return lines.

Unique patented internal design

The RFG Nozzle utilizes a patented internal helix design based on fluid dynamics. Instead of a fixed jet, the water flow is directed in one of five possible directions, one direction at a time.

This creates a wide, wavy and random flow, similar to a wavemaker, but without moving parts, without noise and without additional heat generation.

• Unique patented internal helix design
• Random flow without moving parts
• No wear, no noise and no extra heat

Easy mounting on Loc-Line®

The 3/4-inch RFG Nozzle is designed to snap directly onto original 3/4-inch Loc-Line® modular hoses. No tools are required, and the nozzle is easy to remove or reposition.

• Suitable for 3/4 inch Loc-Line®
• Quick installation through click connection
• No glue or tape needed

Reef-safe and sustainable

The nozzle is made of high-quality PETG plastic, which is completely reef-safe. This material is resistant to prolonged use in saltwater and suitable for powerful flow.

• Made from reef-safe PETG plastic
• Durable and maintenance-free
• Suitable for freshwater and marine aquariums

Eductor effect

Thanks to the eductor effect, additional water is drawn from the environment, increasing the effective water volume and flow impact without additional energy consumption.

• Draws in extra water
• Greater flow range
• More efficient use of the return pump

Flow recommendations

For best results, it is recommended to use the RFG Nozzle within the flow ranges below.

• Single 3/4″ RFG
  • Minimum: 180–200 GPH (680–757 LPH)
  • Recommended optimal: 420–500+ GPH (1590–1890 LPH)
• Two 3/4″ RFG nozzles
  • Minimum: 400–500 GPH (1500–1890 LPH)
  • Recommended optimal: 700–800+ GPH (2600–3028 LPH)

Summary
