I made this to keep fish from being sucked into my siphon hose. It flows nearly as well as the open ended hose. This is also useful for refilling my aquarium as the slots and holes help to diffuse the water outlet, keeping my plants and substrate stable. Feel free to request modifications and suggestions.
