The aragonite was a holdover from the acquisition by Cemex (and, no doubt, also related to the visibility they'd have when making Caribbean islands disappear). They said there are cheaper sources of play sand and calcium carbonate (such as regionally mined silica sand and lime/limestone in the US. I was in Michigan a couple years ago and saw it at Home Depot by the pallet for $6.50/50# bags. I asked my dad to check on it a year ago so I could get a couple 1,200# pallets shipped to CO. HD said it was no longer available. All they could get was silica/quartz sand.

Also silica sand is fine to use (must rinse)

I do have some silica sand that I was going to use for building DIY live rock. It doesn't pass the vinegar test and.... there is only about 1/3 of a salt bucket amount. You are welcome to it.
I am going out of town this weekend so if you need it before then we will need to set up something quick. Cell phone = 719-661-7421
BTW, why would you want to use silica sand? As a suggestion, if you are going to put it in your tank, I would use crushed coral as a bottom substrate and then put what Southdown sand on top of that to get the depth you want. In any case, let me know. I work up in Denver these days but can set something up early next week.
