I think its better to let it sit for 48 hrs in damp sand.
I m too making LR(well which is Dead right now lol)
What I have read is that you let it sit in FW for 4 weeks(atleast) then 1 week in SW then a water change with SW and leave it unstirred for 3 days then check the pH if its between 7.8-8.2 that's good otherwise get some flow and let it sit for another 4 days.then again check.
After FW if u directly put it in ur tank and if the amount is high as compared to your tank.Then there ll a spike in pH.It is also being tested that curing in Hard alkaline water some what speeds the process but atleast a month is needed for curing.To be on the safe side.
