The sand would be a significant mistake because it would further rob aeration from the soil. Water retention and aeration are directly related to particle size. The reason MG soils are so overly water-retentive is because the particles that make up the soil are too small. I've been studying soils and helping people understand how they work for more than 20 years. If you have the ambition, I'm sure you'll benefit significantly from the information I'll link you to. I've had hundreds of container growers tell me the understanding of the concept I explain was pivotal for them as container gardeners. I hope you find it helpful:

The most recent repost has more information than the one at Dave's, which I'll probably repost again soon due to its length. If you'd rather read that version, you'll find it here - it has more than 2,500 posts to it, which I take as testimony to its perceived value.
