The amount of salt you need to add would make it very undrinkable for a horse. I've tried it in a bucket, it didnt help at all.
Our water tank is black, I really don't think that it helps much. I try to keep it out of the elements, and inside the barn overhang/shelter. I keep buckets in the shelter/stalls as well. Those usually take longer to freeze since they're in the barn. You can tell they don't freeze as quickly, because when the trough freezes, the water in the hanging buckets dissapear. Lucky for us we had a stream at the edge of the pasture, its never frozen yet.
The block of wood is a great idea. I might try that.
