In this project, I designed and built a second mini mega tank in my main fish room in my basement. It is a lot smaller but I like it very much. My mini mega tank is also L shaped. The long part of the L is 28 feet, the short part 18 feet. the front to back of the long part is 6 feet for the first six feet then widens to 10 feet, The front to back of the short part of the L is 10 feet, The tank water height is about 6 feet. It holds around 15,000 gallons.
