Flow recommendations
The 1/4 RFG Nozzle is designed for small 5-gallon or less Nano and Pico aquariums. The "Optimal" GPH recommendation is just a suggested flow rate, so we encourage you to experiment

The 1/4in RFG withe Fluval Spec V/Evo is easy to install. Simply remove the stock nozzle assembly and the included 13mm adapter slip-fits right onto the existing pipe.

• Remove Stock Nozzle
• Assemble the 1/4in RFG to the Adapter
• Press the Nozzle/adapter assembly onto the pipe that protrudes out from the back wall, while supporting the elbow behind the back wall with your other hand.
• Adjust the angle of the nozzle and or rotate the adapter to ensure the nozzle sits below the water line.

Randomizer
The 5 internal fins form a set of spiraling channels. As the water flows through the nozzle, the channels draw the stream of water in one direction or the other. The small amount of interference at the base of the eductor causes the stream to randomly change direction as it exits the nozzle.

Draws in additional water volume
