Well, you are brave.
The gulf of Mexico is the biggest depository of contaminants of the US of A.
The Mississippi River alone accounts for most of the contamination. If we
include Texas, Mexico and Florida, three over industrialized state or
nation, then you don't even know what are you putting in your aquarium.
I guess you need to make constant water changes.
But, if it is working for you, I may go to Virgen Gorda in the Virgin
Islands and bring some of that crystalline water back with me.

I use nothing but NSW I collect from the Gulf of Mexico. I know of at
least 25+ others that do as well and we have yet to have a problem,
with the water or the sand we collect.....On Mon, 4 Dec 2006 11:50:41

I have to add that the great majority of sea dwelling creatures
include in
their life cycle tiny or microscopic larvae and eggs. This stages of
potentially dangerous species may enter your tank unseen. On a
plankton
sample taken near Mona island in Puerto Rico, hundreds of miles away
from
any river or developed area, I found TMTC (Too many to count) species
of
parasitic copepods, Callinectes spp, Panulirus spp, Hermodice spp,
hydroids
and others to include shark eggs.

Would you be willing to ship couple of liters of such water to me?
