Square pattern nozzles as the name suggests, disperse water over a media bed in square pattern making it easier to disperse water evenly throughout the cross sectional area of a vessel. If spaced properly the overlap of water streams and water hitting the tank side wall can be minimized. Nozzles are available with orifices from 3/4"-1 1/2". The nozzles are affixed to a Sch 40 pipe (4"-8") using an optional 2" Pipe adapter and can be extended in length if need be with an extender.
