I went through the first 5 pages of the RC thread again to check. Here are some quotes from Anthony Calfo:

If you have to buy bucket and sand new... the bucket will cost you more

He also states:

A DSB bucket should literally cost less than $20 to make (most of which is the cost of the bulkhead unless you skip that altogether and let the bucket gurgle/overflow its sides while sitting in a large open sump)

If he was referring to aragonite, hook me up with that supplier! He never states what to use, but does give this advise, so I mixed up the part about fusing:

The finer sands are better IMO for NNR.

aragonite only fuses when you allow your pH to drop low and usually rapidly as with misdosing calcium supplements (too much kalk too fast, for example) or having unstable pH (dropping very low at night).

It's easy with good water quality/stability to avoid having aragonite fuse.

I'm so very strict about maintaining a strong and stable pH (8.3-8.6... never lower than 8.3 at night)... I have yet to have aragonite fuse. I recommend high and stable pH for more than a few good reasons aside form this issue.

Also states this about silica sand:

silica is OK for the DSB bucket and use in general.

The issue of leaching silica is generally overstated if an issue at all.

The real disadvantage of silica is its shape. Unlike oolitic sand (round/fluid moving), silica is angular and sharp - it locks in place and packs tight. As long as you prevent solids from accumulating/penetrating... there will be no problem with silica sand here.

For flow, Anthony states:

not much flow is needed... just enough to keep any solids in the stream suspended and moving on/along. Simply observe and increase as/if necessary

SO, from that I take it he steals his aragonite sand, because it is not that cheap. JK, some people have access to Southdown sand which is that cheap.

If you have a few spare hours to read the 30pg post, here is the link:
