This invention is a filtration and aeration apparatus which comprises (a) an elongated tubular member which is closed at its lower end, open at the opposite end, and provided at its lower portion with a plurality of passages which extend through the longitudinal wall of the tubular member and (b) an air delivery means for supplying air to the interior of said tubular member at a point at or slightly below the lowermost level of said passages so that the air is discharged parallel to the length of said tubular member in the interior of said tubular member. Another aspect of this invention is a unique air delivery means which comprises an air tube connected to and extending into a chamber designed to allow air to escape from said chamber through passages in the chamber walls so that the air is discharged through said chamber wall passages in a direction opposite from the direction said air is delivered to said chamber through said air tube.
