I would recomend spending the $15 and just using synthetic salt. It might save you trouble down the line. The people at the aquarium probably use bay water for display tanks housing local organisms. I think the bay water is around 50-56F which is much to cold for reef organisms. I don't know the physiology of all those little creatures in that water but I bet if you increase the temp by 25 degrees its going to do something to their survivability. You might end up with a bloom of some kind or you might end up with water containing lots of organics. Either result is not that good.
Again I dont' know a lot about this but I would just spend the $15 on salt. There are too many variables that can not be controlled when using natural sea water, which is why many of us probably don't do it. Thats my opinion. I could be very wrong as I do not know much about this.
Good luck with everything
