The Vivid Creative Aquatics (VCA) Random Flow Generator Nozzle is a 3D-printed nozzle designed to create a natural, randomized flow pattern in your aquarium. It attaches seamlessly to standard 1/2” or 3/4” Loc-Line tubing, transforming your return flow into a wide, wave-like current without any moving parts. Crafted from reef-safe PETG plastic, this nozzle is both durable and easy to install, snapping into place with the traditional ball-and-socket mechanism. Its patented internal design utilizes a set of five spiraling fins to redirect water flow, enhancing circulation and preventing dead spots in your tank.
