Aquarium system having improved flow controller and methods of use

An aquarium system comprising:

• (a) a tank having an interior volume holding water;
• (b) a pump positioned to pump water in the tank through a filter system;
• and
• (c) a flow control arrangement connected to the pump;
• the flow control arrangement having an aeration control to allow selective adjustment in an amount of aeration of water flowing from the pump and back into the tank;
• wherein the control arrangement includes:
• (i) a main body downstream of the pump;
• the main body having a through hole providing communication into an interior of the main body;
• and
• (ii) an aeration flow dial having an aperture, wherein the aeration flow dial can be rotatably adjustable to control axial alignment of the aperture with the through hole in the main body to selectively adjust a size of a resulting orifice from the interior of the main body to outside of the main body.

A method of aerating water in an aquarium tank;

• the method comprising:
• (a) providing a flow control arrangement having a main body with a through hole providing communication into an interior of the main body;
• and an aeration flow dial connected to the main body;
• the aeration flow dial having an aperture;
• (b) rotating the aeration flow dial to adjust axial alignment of the aperture with the through hole in the main body to selectively adjust a size of a resulting orifice from the interior of the main body to outside of the main body;
• and
• (c) pumping water through the flow control arrangement.
