yeah, but I doubt spiderwomans club's presenter is talking about NaCl probably discussing some of the trace elements in the mixture.
That's correct, the trace elements that our corals, fish and inverts need.
 
ok i mixed it up and i dont know if im the only one but i can smell the salt in the water when i first started up my tank, it seems like i can almost always smell the actual salt in it. after i mixed it i smelled it and i couldnt smell anything but water although the salinity was there. i know, probably odd to smell the water but hey, im a little odd sometimes.

I smell the salt in the water as well, especially when I'm pouring it into the container (the little salt powder flies in the air).
 
ok, the stuff that the friend gave me, had no smell what so ever. even when i poured it so i smelled the actual salt grains, nothing, no smell. im not sure if i trust that.

...whenever you have hardened salt mix you have usually abiotically precipitated out CaCO3, MgCO3, and/or SrCo3...
That's interesting, certainly sounds viable, and above my pay grade. I'll ask Bang Guy to look in on this thread. He seems t oknow a bit about chemistry.

have a friend that used to do sw and they gave me some salt, i dont want to just add it in, its from '04. its still in the original packaging. does it go bad?
If the packaging has stayed airtight and no moisture has entered the package then it should be fine. If there are any clumps then moisture has entered somehow. You can still use the salt but be advised that it will be depleted of Calcium, Alkalinity, and Magnesium. These elements would show up in the mixed water as white dust on the bottom of the mixing container. If it were me I would open it and if it has clumps I'd toss it. If there are no clumps I'd use it.

The statement you quoted is 100% true. A calcium reactor could redissolve these elements but they're not going back into solution using saltwater at a normal PH.

normal being 7 or normal being 8.2?
