Product Description The Random Flow Generator (RFG) Nozzle is designed to create natural, changing water movement in freshwater and marine aquariums without the need for additional powerheads or moving parts. By converting a steady return pump output into a dynamic and randomized flow pattern, the nozzle helps eliminate dead spots, improve circulation, and enhance overall tank health. Unlike traditional return nozzles that produce a constant directional stream, the Random Flow Generator continuously varies the direction of water flow, creating more natural currents that benefit corals, fish, and aquatic plants. The result is improved nutrient distribution, enhanced gas exchange, and more effective waste suspension for filtration. Easy to install and compatible with a variety of aquarium plumbing systems, the RFG nozzle is an excellent upgrade for reef tanks, planted aquariums, and freshwater fish tanks. Random Flow Generator 2 sizes available - 20mm or 25mm Also come with 2 styles - Tornado or Duckbill
