Part of the problem is in your method...here's the link to the method that works....http://www.poolforum.com/pf2/showthread.php?t=191

To aerate your pool, aim your return toward the surface of the water so that it creates ripples. You can buy a cheapie fountain and use that to aerate, or you can put a bunch of kids in the pool to play and splash around, which actually seems to work best!
