ABSTRACT:
An aerator (2) comprises a motor (10) having a propeller (18). A slotted cage (30) surrounds propeller (18) and prevents marine life from being drawn in to propeller (18). Liquid will be ejected from propeller (18) in a horizontally traveling stream which stream is oxygenated by a draft tube (48) having a lower end located adjacent propeller (18). Slotted cage (30) is carried on a support rod (68) to form the structure for supporting aerator (2) in tank (4). Cage (30) prevents marine life from being drawn into the propeller (18) as it is driven.
