Tony and I both really wanted a pond and our turtles were getting too big for their tanks so we decided to make an outdoor pond in our back yard. After lots of trial and error about 6 months worth, I think we've finally got it. It is about 4 feet deep and about 9 or 10 feet long. It was nice to take some time and swim in the fresh clean water before we put the turtles in. Liam is quite the little fishy!
