Nacl H20, my father's best friend from Vietnam has a 300 year old bed and breakfast on Edisto Island in South Carolina. The property is on a tital creek, so he actually has a large salt water pond. It is amazing, I found the craziest fish that would get stranded there with the tide. During parts of the month only a small flow would eb and flo due to the cylce of the moon, so he had some pretty neet lifestock. I would love to make a slat water pond some day, eyeing my swimming pool right now! Kidding, need to hit the lottery for a project like that. I bet there are some guys on the coast here who could put together a DIY salt pond of they were close enough to the water... I know I would try...
