I'm not sure... I used the sand to make my DIY rock too so it's even harder to guess... I would say over 500 lbs. I didn't even buy it all at once I just picked up all the store had every time they got it in stock, and I still have about 100-150lbs outside for when my MTS starts to get out of hand.

Yes salt mix has what you need but you will need to supply the calcium that your reef needs in between water changes, as well as extra alkalinity. If you plan on having a lot of coral I suggest you look closely at the costs of dosing vs. the cost of the sand. FOWLR
I would say any sand would be okay but in a reef I would go with the arganite. But how much buffer is there is still in debate so who knows maybe it is mostly inert. Even with a DSB
you will need to dose calcium and alkalinity in a reef. (when I say reef I'm thinking SPS LPS
that use calcium)
