Deb and Ken,
Good luck on your business venture. Personally speaking, and I dont have a BA or a Masters in Fish, but I am as uneasy about putting a man made fish in my pond as I am about spraying chemicals around it. To me nature, my aerator, and some fish food, grow some damn nice fish, and lots of em. My elbows, lawn mower, tilapia, clean my pond. And having invested time and money and energy trying to learn about my pond I must sit back and listen to Greg Grimes just a wee bit more than a saleswoman trying to sell me a product. Grimes hasn't tried to sell me a thing. My opinion and no offense intended. This whole discussion reeks of a sales pitch.
