Hey DRD II,
I reused the existing styrofoam and peanuts that were in the bucket. It was pretty easy to do, just make sure the wind isn't blowing too hard. I dumped the peanuts into another empty bucket that I had. I dumped the leftover mucky stuff from the SE bucket and then refilled with 0-40-0 granules, that I got from the local co-op. They don't disolve as quickly as the original SE fertilizer, but its kept the bloom going.
When you open it up, the styrofoam and peanuts are on top. I refilled to where the new fertilizer just covers the top slits. You may want to fill just below that, as that is what I plan to do next time. You'll see how its packed and realize that its easy.
G'luck.
