1. An aeration pump system with a 90-degree elbow between an inlet and an outlet comprising:
a tee fitting;
an inlet pipe;
an outlet pipe;
a pump assembly;
the tee fitting comprising a main body and a 90-degree curve channel;
the pump assembly comprising a motor, a shaft, at least one peller, a first shaft-stabilizer, and a second shaft-stabilizer;
the 90-degree curve channel traversing through the main body;
a hydrodynamic internal surface of the 90-degree curve channel being configured for unobstructed non-turbulent fluid flow through a lumen of the 90-degree curve channel;
a perpendicular cross-section at each point along a central path through the 90-degree curve channel being a circular shape;
the inlet pipe being adjacently connected to the main body;
the outlet pipe being adjacently connected to the main body;
the outlet pipe being perpendicularly positioned to the inlet pipe;
the outlet pipe being in fluid communication with the inlet pipe through the 90-degree curve channel;
the motor being adjacently mounted to the main body;
the motor being diametrically opposed to the inlet pipe;
the shaft being operatively coupled to the motor, wherein a rotational energy of the motor is transferred to the shaft;
the first shaft-stabilizer being terminally connected to the inlet pipe, opposite of the main body;
the shaft rotatably traversing through the main body;
the shaft being rotatably mounted to the first shaft-stabilizer;
the at least one peller being laterally connected around the shaft;
the at least one peller being positioned within the inlet pipe;
the second shaft-stabilizer being internally connected to the inlet pipe;
the at least one peller being rotatably positioned within the second shaft-stabilizer; and
the shaft being rotatably mounted to the second shaft-stabilizer.
