If I go that route I will use county well water then. Our water is very hard water and it sounds perfect. I need to go harvest a couple hundred pounds of fish from my current pond setup but having trouble finding the time. Do you put the fish remains n your next garden location for next year for tomatoes, corn etc.? I will reuse the fish remains but in small quantity over a large area. You might look at this thread from last year explaining my past problem with reusing fish which may have been a fluke A fish per Stalk of Corn - #39 by clarkinks. I’m also planning to harvest moss from my current ponds Pond Moss as mulch. I could harvest some smaller bluegill from my current setup to test the system instead of buying fish http://growingfruit.org/t/fishing-on-4th-of-july-weekend-how-is-your-weekend/6470/13
