What is claimed is:

1. An apparatus for use in aeration/mixing of a fluid, the apparatus comprising:
a tubular drive shaft having a first end and a second end wherein the first end is coupled to a selectively rotatable power source;
a compressed air source in fluid communication with the tubular drive shaft;
a first propeller having a propeller shaft coupled to second end of the tubular drive shaft; and
an atomizing mechanism located proximate the propeller shaft.

2. The apparatus of claim 1, wherein the atomizing mechanism is coupled to the propeller shaft.

3. The apparatus of claim 1, wherein the atomizing mechanism further comprises:
a plurality of generally flat members spaced radially about the end of the propeller shaft, extending longitudinally outward from the end of the shaft.

4. The apparatus of claim 3, wherein the generally flat members extend inward towards the central longitudinal axis of the shaft.

5. The apparatus of claim 1, further comprising:
a second propeller having a propeller shaft positioned between the first propeller and the second end of the tubular drive shaft.

6. The apparatus of claim 5, wherein the second propeller is larger than the first propeller.

7. The apparatus of claim 5, wherein a spacer is located between the first propeller and the second propeller.

8. The apparatus of claim 7, wherein the atomizing mechanism is integral with the first propeller.

9. In a propeller type aerator apparatus for aeration of a fluid including a tubular shaft having a proximal and a distal end, with a motor coupled to the proximal end, and a first propeller disposed proximate the distal end, the improvement comprising:
a generally tubular housing covering the shaft having an opening;
a compressed air source coupled to the opening;
an air intake hole located along the tubular shaft, in fluid communication with the opening; and

an atomizer located proximate the first propeller.

10. The apparatus of claim 9, the improvement further comprising:
a spacer disposed between the first propeller and the atomizer.

11. The apparatus of claim 10, the improvement further comprising:
a second propeller positioned between the spacer and the atomizer.

12. The apparatus of claim 11, wherein the atomizer is directly coupled to the second propeller.

13. The apparatus of claim 11, wherein the second propeller is smaller than the first propeller.

14. The apparatus of claim 11, wherein the second propeller directs fluid flow at the atomizer.

15. The apparatus of claim 11, wherein the atomizer mixes fluid with the compressed air exiting the second propeller to form fine bubbles.

16. A float support apparatus for supporting an aeration apparatus, the float support apparatus comprising:
a generally U-shaped float base having a deck area; and a support frame for supporting an aeration apparatus from the float base.

17. The apparatus of claim 16, wherein the float base is constructed from two symmetrically shaped sides connected together.

18. The apparatus of claim 16, wherein the float base is constructed of a metallic frame filled with foam.

19. The apparatus of claim 16, wherein the support frame further includes mounting brackets for adjustably suspending the aeration apparatus over the opening in the U-shaped float base.
