Aqua One Aqua Nano 25 Spray-Bar and Venturi Pack

Use the small length of flexible hose provided to add either a short under-water spray bar or bubbling venturi outlet to your Aqua One Aqua Nano 25. The spray bar is great for reducing the water pressure in the aquarium making it more suitable for slow moving varieties such as Siamese fighters (betta) and may be angled up towards the surface or down towards the bottom, while the venturi outlet allows a few bubbles to be injected into the clean water outlet improving aeration in your set up.
