That being said, why are you using old sand? That stuff is a nitrate trap when reused as all kinds of uneaten food and poop builds up in our systems over time.
I made that mistake of using sand from another set-up.....ended up having to completely redo the substrate.
Keep the rock alive, maybe toss a damsel in the container to keep it "alive" and get new sand when it's time to set-up.
and sand kept in a bucket will quickly go nasty in the bottom half.
keep in mind that even with "live" rock and sand, you will still need to properly cycle your set-up so keeping the "live" sand presents more negatives than positives.
