Have you tried adding a little DE to your sand filter? Many of us with sand filters do and it helps to filter out the really small stuff. Check out the sticky in the following link.

Have you checked to make sure that your pump isn't too big for the filter, forcing sand back out into the pool?

Jan may be right. Many pool stores sell pumps to customers that are way too powerful for their pool size and filter size. Just because it came as a kit does not mean that it is a good match. Many customers think that because they got a bigger pump means it is gonna clean better when in fact, too big of a pump will not clean as well as Jan noted above.
