Starting up a 25ish gallon bow front that i plan on just having as a frag tank to grow coral for my future big tank.

Just picked it up today and it had been stored with sand and some saltwater still in it.
The sand was all crystalized with dried salt, do you think I can still use the sand if i rinse it out some?

Pics to come, but its probably going to be a slow build and a thread FULL of questions.
