Looking at a number of different planted tanks I can see all the way around the back edge and there is no filter inlet or outlet tubes. For example, jan 2008 TFH magazine had a 7 page spread of the International aquatic plants contest. There was no hardware to be seen in any of the tanks. Are the tubes and pumps takes out for the photos? I know some can be hidden in corners but was wondering about the tanks you can see all the way around the back glass. Thanks in advance.
