The Aquario Neo Flow comes in a set of inlet and outlet pipes for the planted aquarium. Made from PETG, Aquario Neo Flow lily pipes are stronger than acrylic and transparent like glass without the fragility. Both the inflow and outflow pieces can be easily disconnected and rotated, allowing for easy cleaning during routine maintenance and a full 360° for directional flow adjustments. PETG elasticity allows Neo Flow lily pipes to be cut if desired, allowing aquarists to customize sizing to accommodate a wide range of aquarium tank sizes. It should be noted that Neo Flow Lily Pipes, although stronger than acrylic, may still be damaged if and when unnecessary force is used when handling the pipes.
