Includes a Single 2″ RFG Nozzle for 2" PVC
Flow recommendationsThe RFG Nozzle will handle far more flow than the "Optimal" GPH recommendations, so we encourage you to experiment and test the limits of the RFG Nozzles.
RandomizerThe 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.
EductorDraws in additional water volume
Easy-Snap FittingSnaps onto a standard loc-line fitting with ease. No tool required.
What’s the purpose of the RFG NozzleThe RFG Nozzle is designed to provide a more random flow pattern in your aquarium. Instead of just producing a laminar flow pattern like most aquarium nozzles, the unique internal shape of the RFG Nozzle causes the water flow to randomly change direction as it exits the nozzle.
How much flow does the RFG need?The RFG nozzle will create a random flow pattern at just about any flow rate, but because of the way it works it does defuse the flow to some extent. Becuase of this, we have our minimum flow rate recommendations and what we call our “optimal” flow rates for the 1/2in, 3/4in and 1in RFG Nozzles.Our optimal recommendations produce what we feel is a good balance between the total GPH supplied to the nozzle and intensity and rate at which the nozzle changes the stream direction. The RFG Nozzle will handle far more flow than than the “Optimal” recommendations, so we encourage you to experiment and test the limits of the RFG Nozzles.
