This is going to be a slow going winter project. The plan is a 450g tank with a 55g plastic drum as my filter with a 3000gph pump. My only concerns are heating in the winter. This is going to be for my TSN and Arowana. I will most likely add a few other big cats in there. Here are a few drawings of it and the dimensions are 120'' Long X 30'' Wide X 36'' tall filled to about 30''s
