Hi Danny, your system looks great its the ChopMk2 design from Murry Hallam if I am correct. I have all his videos but I don't have the plans to build this set up. If you want them I'll share my Dropbox with you. I am planning to build it in my backyard. Your chicken coop and pen looks great. Its really motivating to see it! I am curious on your fish selection. Why did you use Hybrid Bluegill fish vs Tilapia?
