WELCOME TO AA!!
Please do not cycle your tank with live animals. (It doesn't sound like you are planning on it, but I like to put it out there).
I would fill up the tank with plain water, just to test for leaks, there is no point in wasting the SW
, in the event there is a leak. Either way is ok...
I would rinse the sand in FW
to get out the smaller particles. Add the sand, then the base/LR
What size tank?
I would suggest using a raw, unseasoned shrimp, from your local grocery store to help the cycle start (1 shrimp per 30gallons is usually suggested). Of course, depending on how much LR
you have, that may be enough to kick start the cycle.
Do you already have a test kit?
I find this place awesome for dry goods:

This will depend on how much LR
per base you have, water conditions.
