I did just this couple of years ago. Had two pools and kept one of them.....had grand ideas to link them via a small "stream".
I used a mixture of garden compost, stacked lawn turves, garden soil, dried cow manure and other bought composts. It has produced a very rich soil.....added organic fertilizer too.....that has successfully become an attractive herbaceous border.
I used good quantities of soil from my veg patch too.......replacing with mushroom compost......
