DITTO SOB - very fine sand will be a detrement rather than an enhancement to your soil. When I encountered clay soil while landscaping I used a combination of compost and mason sand. River sand, washed river sand and play sand were all to fine. Do a test and rub different types of sand between your fingers. You will feel the difference. Coarse is better.
Even in non-clay soil fine sand will turn to clay. Not good.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant. ~Author Unknown
