1 - 2 miles is too close for my liking. When you get to clean water, you'll know. Even the "gin" clean water isn't something I'd feel safe putting in, the cobalt blue is the prime water. Tackle shops use water by their docks for display tanks but there's nothing fancy in the tanks either and if the fish dies, well they just catch more. I'm assuming you don't have bluefish and fluke in your tank.
