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?
