Hello i'm a new member and have spent my summer digging a sping fed pond with a pick and shovel. Pond size is 20' by 50'with an average depth of 2.5'. the water is pretty acidic because we live in an old mining town and i can only stock brook trout i recently put in 20 brook trout 12 in A peice. so how fast and how big will they get in a small pond like mine my goal is 20 in is this feasible. any imformation is much apriciated.
