VCA RFG (Random Flow Generator) Nozzle
Vivid Creative Aquatics revolutionary design uses a set of 5 fins in a spiraling design that channels the water in from one direction at the base of the eductor and then out of the nozzle a different direction. The small amount of interference at the base of the eductor helps create a random change in the intake affecting the flows path exiting the nozzle. The new Flex Series of RFG nozzles are constructed of extremely durable and flexible reef-safe TPU (Thermoplastic Polyurethane), making them directly compatible with a wider range of aquariums and modular hose designs.
