Square salt buckets

No Erik I was correct:

But it is as literal as it sounds: having your DSB in a large bucket or garbage can rather than in a display. It can stay unlit and needs little or no servicing. Just a stream of water flowing atop it. The vessel is to be filled nearly to the top with only a few inches of water running above it. A five gallon bucket will hold about 60lbs of oolitic sand and service perhaps a 90-120 gallon aquarium (larger tanks with lighter bioloads too). Big displays often use a non-toxic plastic garbage can (or food barrel) with more sand of course.

I think theres still conflicting thoughts out there on if its a dsb or a denitrator using sand in a bucket. Where Dr. Ron states
The 8" is the minimum depth that you want to start becoming effective. A DSB is technically 4" or deeper in tank, but you see better results at 8"+ minimum but you get diminishing returns after 18-20"
I guess theres more than one method of bucket DSB
