I didn't take any. I found some treated 2x6x10s in the cull pile at home depot. Cut 1 in half for the ends. Made a box with stainless steel screws. Stapled the fabric to it. I floated it out to around 6" of water, which should be 2.5' at pool and staked it so it wouldn't drift. Went to my local rock plant. Had them fill my bed up with a half ton of sand then a half ton of pea gravel on top of that. The pain was walking 5 gallon buckets through the mud to fill it. All in all, it wasn't a terrible experience. I hope these things make a difference. I'll have roughly $80 in each bed.
